Developers: Text Retrieval Engine

The dtSearch Text Retrieval Engine lets you incorporate dtSearch's proven, industrial strength text retrieval technology into your own products for the PC, LAN or Internet.

The Engine uses a simple, high-level interface consisting of four basic functions: one to initialize the Engine; one to deinitialize the Engine; one to build indexes; and one to search indexes.

The Engine supports all of the search features in the dtSearch end-user product - natural language, fuzzy, phonic, Boolean, proximity, numeric range, field, etc.   The Engine also includes access to the same built - in thesaurus as the end - user product for synonym or concept searching.

All dtSearch developer products come with one year free updates and free technical support to a single point of contact in the purchasing organization.
