# Eduction

Eduction is a tool that you can use to extract an entity (a word, phrase, or block of information) from text, based on a pattern you define. The pattern can be a dictionary of names such as people or places. The pattern can also describe what the sequence of text looks like without listing it explicitly, for example, a telephone number. The entities are contained inside grammar files.

When you use Eduction with IDOL Server, Eduction extracts the entities while the document is indexed and adds them into fields for easy retrieval.

The Eduction capability of IDOL Server is described in the Eduction User and Programming Guide.
