Subject Re: Lucene-In-Action book - any details?..
Date Mon, 10 Jul 2006 15:44:33 GMT

You're right - LIA 1st edition was written for Lucene 1.4.x.  All of  
the code works fine with Lucene 1.9 (with deprecation warnings that  
can be safely ignored), but documented tweaks are necessary to get  
the LIA code to compile with Lucene 2.0.

The coverage of the basics and architecture is still current and  
relevant, as well as algorithms, techniques, functionality, and for  
the most part the API as well.  There are some new features in  
1.9/2.0 that, of course, are not covered (if only I had that time  
machine handy).  Otis and I are in the planning stages of the 2nd  
edition, the calm before the storm.  The 2nd edition should see the  
light of day by the end of the year, or perhaps in early '07 - that  
is the best clarity I get from the crystal ball today.

Overall I think those new to Lucene will benefit from Lucene in  
Action 1st edition, and add to that reading Lucene 2.0 CHANGES.txt to  
catch up on API tweaks and new features.
