whitespace is a significant metacharacter to the Queryparser - it is used
to distinguish multiple clauses

Hi Karthik,
I appreciate your quick response.
I guess the next question is how to do strip the text from
PDF/HTML/XML/MSword/PPT/XLS and where it will store for indexing.
What are the other scenarios (like adding files, deleting files) where
we need to execute indexfiles.classs.
Thanks
Prasa
You could also take a look at Solr. From
http://lucene.apache.org/solr/features.html
* Easy ways to pull in data from databases and XML files from local
disk and HTTP sources
* Rich Document Parsing and Indexing (PDF, Word, HTML, etc) using Apache Tika
Sounds just what you need.

Hi one addition:
In the coming Lucene 3.6 there are more safety checks in MMapDirectory so the
SIGSEGV is more unlikely (it tracks cloned index input in a thread safe list on
close). But this only *helps* to find the issue, but does not guarantee that
your JVM crashes, sorry.

Right, you have to ensure (by using the "right" IndexDeletionPolicy)
that no commit is ever removed until all readers open against that
commit have been closed.
"Normally" the filesystem ensures this for us (protects still-open
files from being deleted), but NFS (unfortunately!) lacks such

Hi,
all MultiTermQueries are constant score by default since Lucene 2.9, you can

Hi,
I have an issue with Lucene 2.9.4 and sorting of wildcard queries.
If I set a boost to some documents during indexing like this:

PRODUCT_GROUP:2020*
I don't get results with a high boost value returned before the documents with

The javadocs for ParallelReader say that all indexes must have same
number of docs and all be created and modified the same way. Doesn't
sound like your shards.
I think you need to create a MultiReader on top of the readers for
your individual shards and pass that to the IndexSearcher constructor
I'm not clear exactly what you are asking but I think you will have to
build your TermQuery instances one at a time and that sounds fine, if
it does what you want and is sufficiently fast.
