The full text search index creates an index of all terms in the documents and file names within the Content System. When a search is performed, the system queries this index to find results. This method enhances system performance in that the search query uses a stored set of data, rather than querying all active data on the system for each search request.
Administrators set the time and the duration for the system to rebuild the Full Text Search index on the Full Text Search page. If a rebuild is not complete within the duration set, the index will begin rebuilding next time from the point it left off. For best results, Administrators should always try to allow the system to completely rebuild the search indexes.
Note: If the system has automated backup, check that the settings on the Full Text Settings page do not interfere with the backup.
Note: Full Text Search does not index text from encrypted .pdf documents.
