Field search operator in parentheses

General Discussions - English

What exactly are the rules when the field search operator (Manticore Search Manual: Searching > Full text matching > Operators) is in parentheses? For example

MATCH(' (@title one) two ')

Is this valid altogether? Will “two” be searched for in “title” or everywhere?

Please use explain query to understand it, e.g.:

mysql> drop table if exists t; create table t(title text); explain query t ' (@title one) two '\G
