Got it, I must have installed that perl module with the KitchenSink....

I think I have located the problem code in Search.pm, but someone with more 
code knowledge is needed....

line 327:

       if(! scalar @specs or ! $s->{mv_coordinate}) {

when using text query it never falls through and checks the length of the 
string, actually if you don't use text query as the demo at icdevgroup.org 
doesn't give an error for mv_min_string on an empty search

if the above line is changed to:

       if(! scalar @specs or ! $s->{mv_coordinate} or length($_) 
<$s->{mv_min_string}) {

you get the : Search strings must be at least %s characters. error message, 
but a better solution seems needed....

thoughts....
