[FX.php List] Confusion with 'not equals' search

[Jonathan Schwartz]

Did anyone answer this question?

I was going to answer with what I understand to be the case...that 
fx.php will only execute the last query submitted for a given field, 
and ignore the previous query.  That would render a multiple query on 
a single field non-functional.

Or..perhaps it is the opposite...fx.php accepts just the first query 
and ignores the second.

I wanted to see how more experienced users responded.
