N-Gram Index


This article will provide some information on how to configure eXist-db's ngram index.

Index Configuration

To create an n-gram index, add a <ngram> element directly below the root <index> node of a collection.xconf document:

<collection xmlns="http://exist-db.org/collection-config/1.0"> <index> <lucene> <text qname="SPEECH"> <ignore qname="SPEAKER"/> </text> <text qname="TITLE"/> </lucene> <ngram qname="SPEAKER"/> </index> </collection>

The ngram index only supports index definitions by qname. The path attribute is not supported. There are no additional parameters to be specified.
