REGEXMATCH

The REGEXMATCH field specifier matches documents where a specified field value (the entire value, not just part of it) matches a regular expression. The regular expression matches field values case-insensitively.

NOTE: This field specifier is optimized for MatchType fields, and ParametricType fields when ParametricNumericMapping is TRUE.

Format

FieldText=REGEXMATCH{regex}:fields

`regex`	A regular expression. A document is returned only if the entire field value matches the regular expression.
`fields`	A colon-separated list of field names (there must be no space before or after a colon). A document is returned only if the value in at least one of the fields matches your regular expression.

Examples

In the following example, the COUNTRY field must match either "United Kingdom" or "United States".

FieldText=REGEXMATCH{United (Kingdom|States)}:COUNTRY

The query would not match a document if the COUNTRY field contained the value "The United Kingdom", because the entire value must match the regular expression.

In the following example, the PAGECOUNT or TOTALPAGES field must contain either two or three digits.

FieldText=REGEXMATCH{\d\d\d?}:PAGECOUNT:TOTALPAGES
