Format of search critieria?
 

I noticed that the search strings
"Elvis Presley" Words
and
Elvis Presley Words
yield different results in the Gnutella network. The second one produces lots of hits that do not contain the string "words"...
Is there a format specification for the search string? How do I use wildcards or AND/OR modifiers? Didn't find anything in any FAQ, etc. or in the protocol specs....

Thanks,
Ralph.
(sorry for posting this twice)

The searches use a case insensitive AND of all words on newer clients.
