Subject RE: Adding CLucene as a Lucene subproject
Date Wed, 26 May 2010 23:36:25 GMT
Earwin,

Considering the fact that Lucy is not planning on complementing Lucene's
API, while CLucene's goal is to be a one-by-one port, I would say no
relationship. Also, CLucene is written in C++ and not C.

Re. Sphinx - I'm not familiar enough with it to really comment on this, but
I'd assume this is more of a Lucene vs Sphinx question. Do the prons and
cons, throw in some benchmarks, and then give CLucene a couple of extra
points for being cross-platform, and 5-10 times faster than the equivallent
Lucene version. I had a quick look, and it seems like Lucene is much more
scalable (esp. considering the latest developments) and some even claim that
"Lucene performance is unmatched".

Also, unless a restrictive license isn't a show stopper for you, Sphinx is
released under GPL.

Itamar.

I wonder, what's going to be the relationship between this and Lucy?
Also, how do both of them compare to Sphinx?
