Without search term expansion, search results will only contain results where the words match exactly those used in user search queries. To overcome this problem Sharepoint includes thesaurus files,
The thesaurus files are in XML format and Microsoft state that only system administrators can update, modify, or delete the thesaurus files. Editing the files in Windows NotePad or an XML editor is a slow and error prone process and any errors in the file format or encoding can lead to search working incorrectly. Furthermore it is not easy for the work to be spread among several users.
Kenza is designed for ease of use and can be run directly on the SharePoint server for use by the SharePoint Administrator or on any PC running Windows 7, Vista or XP for use by non-technical staff. Kenza can create multiple thesaurus XML files and includes a merge feature so that files created by different people can easily be combined. Text can be typed in or copy and pasted from other documents or web pages for fast error free production.
Kenza ensures that the file is in the correct format and takes care of empty entries, unwanted white space, punctuation and other special characters automatically. Automatic de-duplication, text cleanup and noise word highlighting assist the user to produce correctly formatted files in record time.
