Use this method to set search facility that is used to match multiple strings in the request or response. Used in the INSERT_BEFORE_ALL, INSERT_AFTER_ALL, REPLACE_ALL, and DELETE_ALL action types. The following search types are supported:
* Text ("text(string)") - A literal string. Example: -search text("hello")
* Regular expression ("regex(reregular exp)") - Pattern that is used to match multiple strings in the request or response. The pattern may be a PCRE-format regular expression with a delimiter that consists of any printable ASCII non-alphanumeric character except for the underscore (_) and space ( ) that is not otherwise used in the expression. Example: -search regex(re~^hello*~) The preceding regular expression can use the tilde (~) as the delimiter because that character does not appear in the regular expression itself.
* XPath ("xpath(xpxpath expression)") - An XPath expression to search XML. The delimiter has the same rules as for regex. Example: -search xpath(xp%/a/b%)
* JSON ("xpath_json(xpxpath expression)") - An XPath expression to search JSON. The delimiter has the same rules as for regex. Example: -search xpath_json(xp%/a/b%)
NOTE: JSON searches use the same syntax as XPath searches, but operate on JSON files instead of standard XML files.
* HTML ("xpath_html(xpxpath expression)") - An XPath expression to search HTML. The delimiter has the same rules as for regex. Example: -search xpath_html(xp%/html/body%)
NOTE: HTML searches use the same syntax as XPath searches, but operate on HTML files instead of standard XML files; HTML 5 rules for the file syntax are used; HTML 4 and later are supported.
* Patset ("patset(patset)") - A predefined pattern set. Example: -search patset("patset1").
* Datset ("dataset(dataset)") - A predefined dataset. Example: -search dataset("dataset1").
* AVP ("avp(avp number)") - AVP number that is used to match multiple AVPs in a Diameter/Radius Message. Example: -search avp(999)

Note: for all these the TARGET prefix can be used in the replacement expression to specify the text that was selected by the -search parameter, optionally adjusted by the -refineSearch parameter.
Example: TARGET.BEFORE_STR(",")
