Re: Re: [Team] search library battle royale [draft]

Lucene: it slices, it dices, it's twice as nice as...well, htDig 3.1 for 
sure.

Here are a couple reasons why Lucene is the Battle Royale champ in my eyes:

* Powerful searching features: 
http://lucene.apache.org/java/docs/queryparsersyntax.html - let's see 
the other kids do all this.

* When was the last time you searched Unicode characters on The Mail 
Archive?  That's right, never!  But with our experiemental Lucene 
interface, you can: 
http://www.mail-archive.com/lucene/search.py?list=freebsd-users-jp%40jp.freebsd.org&query=%E3%81%95%E3%82%93


Downside/upside: Xapian has the nice Omega web interface.  Lucene has 
Nutch, but for a few reasons it didn't fit our needs.  So, our web 
interface is coded up by hand using PyLucene/modpython.  The downside is 
that it meant a bit more work for us, but the upside is complete 
configurability.  Missing right now is paging - it simply displays the 
best 100 matches.

Downside: our PyLucene interface doesn't have a killer name like Omega.
