Hi:
The default buffer size (for docid,score etc) is 32 in TermScorer.
We have a large index with some terms to have very dense doc sets. By
increasing the buffer size we see very dramatic performance improvements.
With our index (may not be typical), here are some numbers with buffer
Erick,
Thanks for taking a moment to address my question. I suspect the
confusion expressed in the answer was from a slight transcription error that
added additional punctuation.
In your reply, the query was expressed using fields (note the use of extra
use of colons that changes the query m
I guess my first question, based on your statement that you ran
checkindex from a different machine would be whether you have
the same version of Lucene installed on both machines? And how
did you get your index where it is now? did you optmize it in place
or did you optimize it somewhere else and
Greetings all. I have an index that I have optimized and when I try to open

sorry for the mess... its pretty much untested since i'm doing some pretty
wierd stuff with fastss algorithm.
i hooked it to commons-lang levenshtein for simplicity... i'm pretty busy at
work so if someone wants to improve it that would be helpful
hi,
yes, the results that come back from the lucene index i verify at runtime
before expanding the query. i considered trying to store delete positions as
payloads or something but fastssWC is good enough for me.
i'll see about posting my code today.
