About the keyword index

Discover an introduction to the Main Word Index and the indexed fields in OLIB.

►System Administration> Keyword Indexes

This is the Main Word Index used in the Titles domain and in the OPAC, where the Keyword search searches several fields in the bibliographic record. There is no configuration necessary for this unless you want to change the default installation. The advantages of this approach are:

  • Allows wide range of searching, e.g. Proximity and Phrase Searching
  • Allows choice of fields for indexing to be selected to suit local requirements
  • Provides real time indexing of new Title records
  • Updates the index automatically when items are deleted or modified

The index is maintained by a background task in the database on a regular basis for new, deleted and amended records. It updates the index accordingly.
