The Match service locates an element within the list that matches the given string. The match is not case sensitive, but if the Option parameter is "MatchAll" (which is the default), then a match succeeds only when the string matches the entire element. If the Option parameter is set to "MatchAnywhere", then the first element contain the given string anywhere within itself is a match. For example, "Branded" is considered a match for "AND" because "and" appears within the element. When a match is found, the FieldPos, ValuePos, and SubValuePos parameters are set to the position of the match. If no match is found, all three parameters will be set to 0. "MatchAnywhere" is the default if this parameter is omitted.

IMPORTANT: The Match service will begin searching at the position specified in the FieldPos, ValuePos, and SubValuePos parameters. Set these to 1, or 0, to search from the beginning of the array. However, if you need to start the search elsewhere, then set the position in advance. For example, setting FieldPos to 3 tells the Match service to start looking for matches in field 3.
