Create word lists and a user-defined character set

To prevent stopwords from being indexed, always associate a stopword list with an etx index. This section describes how to create a stopword list based on the file of stopwords provided by the IBM® Informix® Excalibur Text Search DataBlade® module.

The Informix Excalibur Text Search DataBlade Module provides three built-in character sets (ASCII, ISO, and OVERLAP_ISO) that are used to determine which characters are indexed. If the character sets provided do not index the desired characters, you can define your own character set.

This section describes how to create a user-defined character set that is similar to the ASCII character set but also indexes hyphens.
