96Re: Specific search tuning question in FAST ESP
- Feb 7, 2008While the approach may seem a little cumbersome, remember, searching
an inverted index, which is a requirement for any sort of
scalability, is rather unlike a database query or a perl script. If
my memory serves, Autonomy and, until recently, Verity, did not
offer much more in this regard.

No utility to say "One word results only", huh? Is there maybe a way
in the rules to do a kind of regular expression that looks for a
line or field terminator after "snow"? Or at least to say "Find snow
without another alphanumeric character or space after or before it?
For example, such a matching expression using perl might be /^snow$/
or /^snow(\n|\r|\f)$/ or simply that the string must equal "=" the
query rather than be an approximate match "=~" to it.
