Free Wbntor query limitations?

[Thunderstone]

I am trying to limit searches using the logic you recommend (e.g. -
w/sent, w/line, AND NOT OR...) and I am often getting this:
"115 Jun 17 10:03:05 /webinator/searchall:132: 'delimiters' not allowed
in query" in addition to other unexpected search results.

Does the free Webinator have limits on search paramaters?

thanks

If you want to use logic and proximity in the query instead of
from the "options" form you need to turn off some query protections.
Particularly alpostproc alintersects alnot alwithin.
