This is an enhancement request.
There are 4 default search criteria for every field in advanced Search. Those criteria only make sense for text fields , and it can take a long time to set the appropriate criteria for all the fields on a complicated search form.
The best defaults for integer, decimal, date, datetime or timestamp fields is:
==, !=, >, >=, <, <=, and Between.
ALTERNATE:
Make the criteria list multi-select so that I can select the ones I want turned on/off and toggle them.
