Regexp query #

Returns documents that contain terms matching a regular expression.

A regular expression is a way to match patterns in data using placeholder characters, called operators. For a list of operators supported by the regexp query, see Regular expression syntax.

Examples #

The following search returns documents where the org.id field contains any term that begins with in and ends with y. The .* operators match any characters of any length, including no characters. Matching terms can include ini, inni, and infini.
