=item B<Description>
Returns SQL syntax for performing a full text search for specified text
on a given column.
Returns one or two SQL expressions for performing a full text search for
specified text on a given column.
If one value is returned, it is a numeric expression that indicates
a match with a positive value and a non-match with zero. In this case,
the DB must support casting numeric expresions to booleans.
If two values are returned, then the first value is a boolean expression
that indicates the presence of a match, and the second value is a numeric
expression that can be used for ranking.
There is a ANSI SQL version of this method implemented using LIKE operator,
but it's not a real full text search. DB specific modules should override
