query on *.* vs 6.*

Hi,

I have webinator and the following query returns 5384 results (http://powell.mit.edu/Library/Search.as ... 10k&jump=0)

but this one returns nothing (http://powell.mit.edu/Library/Search.as ... 10k&jump=0)

Isn't the 2nd query a superset of the first and should return the same or more results? I have the following settings:

<apicp alpostproc 1>
<apicp allinear 1>
<apicp alequivs 1>
<apicp alintersects 1>
<apicp alnot 1>
<apicp alwithin 1>
<apicp alwild 1>

Thanks

Neither of those works for me I just get completely blank pages. Vortex is probably generating a query protection error or warning in it's html output. That will tell you where the problem is. It's probably related to qminwordlen. Also "*.*" is pointless, just search for ".". Queries with a leading * can't take advantage of an index and may be slow depending on your data size.
