Using Verity as an indexer

Version 1.3 of Harvest includes support for using Verity Inc.'s Topic indexing engine with the broker. In order to use Topic with Harvest, a license must be purchased from Verity. At this point, Harvest does not make use of all features in the Topic engine. However, does include a number of features that make it attractive:

• Background indexing: the broker will continue to service requests as new objects are added to the database.

• Matched lines (or Highlights): lines containing query terms are displayed with the result set.

• Result set ranking

• Flexible query operations such as proximity, stemming, and thesaurus.
