Description:
May we please have a .cnf configurable option for GWS_IN_USE GWS_FREQ?  The "50% threshold" option seems not to fit in many databases, and modifying source code and recompiling can be difficult and time consuming.

My opinion is that too many results is more relevant than mysteriously receiving no results.  

Thank you in advance!

How to repeat:
select column-name, match (column-names) against ('frequently-used-word') from table-name; 

Running this fulltext query with a word used in over 50% of the records will produce no results.

Suggested fix:
My suggestion is to make "GWS_PROB" the default, then allow administrators to use FREQ (through my.cnf) with LIMIT.

Another suggested fix (although asking a for a lot) would be the ability to configure the threshold level (possibly through my.cnf).  This way, the administrator could configure a "75% threshold" or any other percentage (including 0%) if he or she so desires.

Currently you can use boolean mode.
