Re: [cgiapp] Plucene or Xapian?

["Timothy Appnel" <suppressed>]

I've built something with Plucene and it has "issues" that I would not
suggest using it. Its terrible slow and resource intensive. I also
think development has essentially stopped at this point. (I'm not sure
about that.)

KinoSearch shows a great deal of promise IMHO though its a bit
nascent. Its developer, Marvin Humphrey, is one of the founding
members of the Apache Lucy project[1]. The work being done to
KinoSearch comes from that work and will eventually become part of
Lucy.

Here are some benchmarks presented at OSCON 2006[2] of Lucene style
engines indexing 19043 news articles drawn from the Reuters 21578
collection, Distribution 1.0.

Lucene 1.9.1 57.71 secs
KinoSearch 0.09 62.91 secs
Plucene 1.24 1931  secs

I suspect that KinoSearch has gotten even a touch faster since then.

You'll want to use version 0.2 which is currently in a developers
release. Versions prior to 0.2 were considered alphas whose API and
index format are subject to compatibility breaks with v0.2 going
forward.

Hope that helps.
