Word Definition

Syntax: one or more regular expressions (REX), each on a separate line

Sets the word matching expression(s). Each line is a regular expression defining what is considered a word within the textual content of the retrieved documents during the index process. The default expressions index normal words and some special items such as domain names.

You may supply multiple expressions, one per line, if you can't define your idea of all possible words in one expression.

For example, >>\alpha=\alnum{1,20} will index ``words'' beginning with an alphabetic character followed by 1 to 20 alphabetic or numeric characters.

Changing the word definition with Update instead of Update and GO will cause the existing search index on the data to be dropped and rebuilt. The database will not be searchable during the short time that the index is being rebuilt.
