This table lists 60 vendors.  Not all are search software vendors. Also included are some vendors providing a range of ancillary services and some of the many vendors providing data analysis and business intelligence software. In the case of Google, HP(Autonomy)  IBM, Microsoft, Oracle, OpenText and SAP no URL is listed as the pages for search products tend to be far from permanent. This table was last updated in July 2017.

If there is any company that feels that they should be on the list please contact us. However the final decision on which vendors are included will be made by Intranet Focus Ltd.

No warranty, explicit or implied, is given by Intranet Focus Ltd as to the quality of the products listed. Search software should always be selected on the basis of a detailed profile of user requirements, not just a list of functional requirements. We will be pleased to support the process and help our clients come to the best decision taking into account a wide range of factors.
