8 top enterprise search engines

Whether an organization wants to improve its internal or external search strategies, an enterprise search engine can help users find information and protect data more easily.

Organizations create massive volumes of data, and users often struggle to find information they need. Whether it's branding materials, technical documents or emails, the average employee spends a good portion of their work week looking for information or tracking down someone who knows where it is.

Enterprise search engines emerged to simplify how organizations present information to users, whether they browse the company website as a prospect or search internal documents as an employee. The data they need could live inside a database, content management system (CMS) or an email server, and the search engine functions much like a consumer-facing engine, such as Google, to search for keywords or terms the user inputs. Modern enterprise search engines often use AI technology, like natural language processing (NLP) and machine learning (ML), to provide a streamlined experience.

For enterprise content and data management leaders who want to improve their content management strategies, they should review the top eight enterprise search engines that can help.

These products were selected based on reports from leading analyst firms, such as Gartner and Forrester, and user reviews on G2 and Capterra, plus additional research by TechTarget editors.
