help finding docs, creating analyzer objects

[Eric Haszlakiewicz <EH...@transunion.com>]

I'm been having a hard time finding any kind of reasonable
documentation 
on lucene.  It seems that the javadocs are mostly empty, and the stuff
on 
the wiki really doesn't explain anything.  Is there a better place to
be looking?

So far, I've managed to get some basic stuff working.  Now I'm trying
to 
figure out where to get a spanish analyzer from.  I found a message 
from 2003 where someone tried to contribute one, but it got rejected 
because there's something called a snowball analyzer that supposedly 
supports spanish, but again, I couldn't find any documentation for how
to 
use it.  The closest I could find was a snippet of code that did this:

        Analyzer analyzer = new SnowballAnalyzer("Spanish");
Is that correct?  How do I know what name to pass to the constructor?

I tried building some code with that, but it seems the jar file (lucene
2.0.0) 
is missing all the snowball stuff.  It doesn't seem to be in the source
zip file
either, so I'm not too surprised that it's not in the jar file, but
(perhaps 
you detect a trend here) I couldn't find any documentation about where

to get a complete jar file from.  Where can I get this from?

Hi Eric,

I'm sorry you are not finding what you need.   The snowball analyzers  
come in a separate jar, in the release zip, under the contrib/ 
snowball directory.  You may also want/need the analyzers in contrib/ 
analyzers for other languages.  The README delivered w/ the release  
probably should be updated to state that this is where you find the  
additional analyzers.  I will do that shortly (which doesn't help  
you, but should help others going forward)

Have you gone through the demo and the "Getting Started" section:  
http://lucene.apache.org/java/docs/gettingstarted.html ?

There are a number of articles, presentations and books available,  
many of which are listed at http://wiki.apache.org/jakarta-lucene/ 
Resources

Additionally, the "Lucene In Action" book is quite good and most of  
it still applies to 2.0 (I think the URL is www.lucenebook.com).

Also, please add an issue or two for any specific places you feel are  
unclear or are lacking and hopefully they can be addressed.  Patches  
are always welcome, especially for documentation and the Wiki only  
requires a username password to edit.
