What is intranet search?
Intranet search is the engine that powers information discovery within an organization’s digital ecosystem. Unlike public search engines, intranet search is tailored to internal content – documents, policies, people, and knowledge bases – enabling employees to find what they need, when they need it. In large enterprises, where information sprawls across multiple repositories and platforms, intranet search is the connective tissue that prevents knowledge from becoming fragmented or lost.
The business impact of intranet search
A study from McKinsey has shown that poor search can be a real issue, with employees spending an average of 1.8 hours per day searching for information. A more recent study from Unily honed in on enterprises with frontline workers – showing this can lead to an economic cost of over $80 billion.

The economic cost of frontline friction
Here are some of the benefits of high-quality intranet search:
1. Reduces friction
Employees spend less time hunting for information and more time acting on it. For example, 53% of National Grid employees save more than 30 minutes a week thanks to good platform search. Multiply that across global teams and the business case writes itself.
2. Increases productivity
Reducing friction in knowledge discovery leads to tangible productivity gains. This isn’t just about saving time – it’s about enabling more impactful work. For example, Flight Centre utilized one-click access to external business systems from within its Employee Experience Platform (EXP). This meant people could quickly find resources and information using keywords, delivering a significant productivity boost.
3. Supports decision-making
Better access to information enables leaders and teams to make better, data-driven decisions. This is especially crucial at a time of constant market shifts and volatility. Strategic pivots may be constantly required, and have the information you need at your fingertips ensures that these can be done sharply.
4. Breaks down silos
Unified search bridges departmental and geographic divides. Whether it’s a frontline worker looking for the right head office contact, or someone needing to work with a colleague at the opposite end of the globe – better search fosters a culture of collaboration. This makes institutional knowledge more accessible and actionable.
5. Prevents compliance issues
Search doesn’t just boost efficiency – it protects the business. With the right platform, you can also make use of things like role-based access control. This means certain data is discoverable only by certain people.
Unily’s study showed 71% of frontline workers admit to using personal devices or non-company apps to collaborate and share company information. Effective search, governed properly, reduces that exposure.
Key intranet search functionality: What enterprises should look for
Unily was ranked first for both Application Portals and Knowledge Services in Gartner's Critical Capabilities report - application portals looked at "easy, unified, personalized, and orchestrated access to business systems and processes”, whilst knowledge services looked more broadly at content management, search, navigation, and ultimately; insights.
Unily ranks first in all Use Cases in the 2024 Gartner® Critical Capabilities™ for Intranet Packaged Solutions.
For enterprises, intranet search must go beyond basic keyword matching. The following features are essential for a modern, high-performing solution:
Natural Language Processing (NLP)
Employees don’t think in Boolean queries. NLP empowers your search engine to understand context, synonyms, and user intent. This produces relevant results even for complex queries.
Personalization
Personalized results based on job role, location, and behavior increase relevance to employees. A good EXP automatically tailors results by recognizing who the user is, what they need, and how they work.
Advanced filtering
This enables users to refine results by date, document type, department, and more. As a results, they can find information faster, and drill down into content without being overwhelmed. This can also prevent the digital noise issue which is so prevalent in the modern workplace.
Integrated search
A truly unified search experience means the search needs to be integrated beyond the intranet. Many enterprises we speak to use things like SharePoint, Google Workspace, and Salesforce, to name a few – and for them, an integrated search experience is a must-have.
Intelligent autocomplete and suggestions
A good intranet search begins before a user hits enter. Things like smart suggestions and autocomplete suggestions surface content even as users type, powered by historical data and popular search behavior. This directs users to the right information quickly, reducing errors and search fatigue.
Analytics and optimization
This is less about the user experience, and more about the team behind the intranet. Real-time analytics enables you to understand what users are searching for, what they’re not finding, and how to improve intranet search UX over time.
Intranet search engines: types, technologies, and trends
Enterprises generally face a choice between on-premises and cloud-based intranet search engines, each with distinct advantages depending on organizational priorities, industry requirements, and IT infrastructure.
On-premises intranet search engines
On-premises intranet search solutions provide full control over the architecture, data governance, and customization capabilities. For industries with strict regulatory requirements, this be necessary to meet compliance mandates or internal risk thresholds.
However, this approach comes with heavy burdens. Organizations must invest in servers, infrastructure, security, and dedicated IT staff to maintain and update the system. Scalability becomes a challenge as data volume grows, and system upgrades are often time-consuming and costly. Plus, security is entirely the organization’s responsibility, which can be a double-edged sword.
Cloud-based intranet search
Cloud-based intranet search solutions offer significant advantages in agility, scalability, and total cost of ownership. These platforms are designed to scale with your business, offering elastic compute power and storage that adjusts to demand.
Cloud intranet search engines benefit from continuous updates, faster innovation cycles, and enterprise-grade security provided by cloud vendors such as Microsoft Azure or AWS. Many of these platforms are also certified for compliance with key regulations (e.g., ISO 27001, SOC 2, GDPR).
Because cloud-based solutions are hosted externally, IT teams are freed from the burden of system maintenance and updates. This allows organizations to reallocate resources toward strategic initiatives rather than infrastructure.
Ultimately, the decision hinges on your organization’s digital maturity, regulatory environment, and appetite for scalability. Increasingly, hybrid models are emerging - where sensitive content resides on-premises while leveraging cloud search capabilities for less-restricted data. Unily’s platform is built with the flexibility to support both models, empowering enterprises to choose what works best without compromise.
AI and machine learning in intranet search
Artificial intelligence is revolutionizing intranet search by making it smarter, faster, and more intuitive. Machine learning algorithms analyze user interactions, continuously improving the relevance and accuracy of search results.
Here are some of the things organizations are utilizing AI for in terms of their intranet search functionality.
- Predictive Search: Anticipates user needs, suggesting content and resources proactively.
- Personalization: Adapts to individual preferences, roles, and behaviors, delivering a tailored experience.
- Tech stack integration: Connects with enterprise applications, breaking down silos and supporting end-to-end workflows.
These capabilities turn search into a competitive advantage. For example, if a sales director frequently accesses competitive analysis documents during planning season, AI can begin recommending the latest intel at the start of each quarter – reducing friction and increasing time-to-insight.
Unily’s AI-driven intranet search harnesses these innovations, ensuring every employee has instant access to the knowledge they need to excel. From generative content, to Netflix-style content recommendations, to enhanced translation and video capability, enterprises can now bring employee experience into the world of AI.

Emerging trends to watch in intranet search
As the modern digital workplace continues to evolve, intranet search is being redefined by powerful innovations. Enterprises that anticipate and invest in these trends will position themselves at the forefront of productivity, security, and user experience. Here are some critical developments shaping the future of intranet search:
Greater integration of voice search functionality
As digital interactions become more conversational, voice search is emerging as a powerful tool – especially for frontline and remote workers who need hands-free, on-the-go access to information. Fueled by advances in natural language processing (NLP), voice-enabled intranet search allows users to interact with their digital workplace as they would with a colleague.
Voice search can improve accessibility, support inclusivity, and enhance user experience – especially when paired with AI.
Enhanced security through blockchain technology
As cyber threats grow more sophisticated, so too must the mechanisms that protect sensitive enterprise data. While traditional encryption methods remain key, blockchain is emerging as a next-generation technology to bolster security, transparency, and traceability in intranet search systems.
Blockchain’s decentralized nature allows for clear audit trails, making it easier to verify data access, track content modification, and ensure search integrity. This is particularly relevant for highly regulated industries like finance and healthcare.
While enterprise-wide blockchain adoption is still maturing, the groundwork is being laid. Platforms like Unily are built with extensibility in mind, ensuring your intranet search architecture is ready to support emerging security innovations – including blockchain-enhanced governance – when required.
Intranet search best practices for enterprises
A high-performing search experience doesn’t happen by accident – it requires continuous care. Here are some best practices for organizations to follow.
Personalization and user experience in intranet search
Personalization is the key to delivering a search experience that feels intuitive and valuable to every employee. Modern employees expect search to behave like their favorite consumer platforms – smart, responsive, and context-aware. By leveraging user data – whether it’s roles, locations, departments, or past behavior – search results can be tailored to individual needs, driving engagement and productivity.
Here are some examples:
Custom suggestions
This is where an intranet search engine proactively recommends relevant content, documents, or colleagues based on contextual signals. For instance, a project manager logging in during a product launch phase might see recent campaign assets, relevant legal documentation, and the team calendar – all without typing a word.
Dynamic interfaces
By adapting the intranet search layout to reflect user roles and behavior, organizations can simplify the UX for people and accelerate task completion. For example, engineers may receive filters for source code repositories, while HR managers may see categories for policy documents or onboarding materials.
Privacy controls
This is about balancing intelligence with autonomy. Employees can adjust their personalization settings, controlling how much their past behavior or profile data influences search results. This transparency fosters trust while ensuring relevance.
Multilingual and regional adaptation
This is especially critical for multinational teams navigating different legal, cultural, and operational contexts. One of the reasons Unily is trusted by global enterprises is due to its ability to support language preferences and regional settings, offering search results localized to geography or office.
Unily’s search experience is built around these principles of personalization and adaptability. It recognizes that employees don’t just want fast answers – they want fast answers that fit their needs. This is how intranet search becomes a strategic driver of engagement, efficiency, and enterprise success.
Integrating intranet search with other systems
A unified search experience is essential for breaking down information silos and enabling seamless workflows across the enterprise. Integration with systems like CRM, HRIS, and document management platforms ensures that employees can discover content from multiple sources through a single interface. Here are some of the key elements that are needed for this to happen.
Unified indexing
Aggregating content from across enterprise systems – such as SharePoint, Salesforce, Workday, Google Drive, and internal databases – ensures comprehensive search coverage. A centralized index helps employees locate information quickly, regardless of where it is stored or who created it.
API connectivity
Robust API support allows organizations to integrate search functionality across both legacy and modern systems. This flexibility enables IT teams to build a scalable intranet search architecture that evolves alongside business needs and technological innovation.
Real-time syncing
Integrations should support real-time or near real-time updates, ensuring that search queries return current and accurate information. This is especially important for content that changes frequently, such as HR policies, customer records, or project documentation.
Other best practices
Optimize metadata - Good search starts with good content. Ensure metadata is standardized, tagged consistently, and kept up-to-date.
Implement governance - Define who owns content, how often it should be reviewed, and what retention policies apply. Implement robust, role-based access controls and audit trails to protect sensitive information.
Listen to your users - Collect and act on user feedback to identify gaps and refine search functionality. Also make sure to review failed searches, collect feedback, and prioritize what employees actually need.
Train for search success - Even the smartest search engines need informed users. Offer quick-start guides or in-platform coaching to promote good search behavior – equipping users with the knowledge to leverage advanced search features.
Keep your index fresh - Re-index content when changes occur to ensure results are never outdated.
