Hi,
I am new to Lucene. I find that the output
of the Query.toString() method cannot be parsed
back to the same query. Is it true? If it is
true, I am wondering why not make the output of
Query.toString() parsable to the same query again?
Unless there is something prevent us to do so, such

Hi All,
I have queried and have got a HITS object which is a collection of
documents. I want to find out the centroid of these documents. Centroid =
Top Most 35(for eg)common terms across all the documents in the HITS
object.
Is there any API in Lucene for this?
Thanks in Advance.

Hi Otis, you could use the byTask package - add your-type-of-search-task.
Suffix the new task class name by "Task" - e.g. NewNameTask - and then you
can use the 'command' "NewName" in an alg file.
I am not sure you can extend/reuse the existing ReadTask for this, because

Hi,
I'm looking at benchmarking Paul's
http://issues.apache.org/jira/browse/LUCENE-584 code.
I'd like to compare either:
HitCollector.collect(doc, score) vs. MatchCollector.collect(doc)
or
IndexSearcher.search(Weight, Filter, HitCollector) vs.
IndexSearcher.match(Query, MatchCollector)
..
Xiangyu Jin, a better place to ask is the java-user list. You'll want to
subscribe to that. You didn't mention Similarity/DefaultSimilarity classes.
Maybe that's what you missed.

You shouldn't try to print it out... it's essentially binary :-)

One more thing...
It could optionally be indexed and stored as a String
then contents of the Hits object could be placed into
a Collection with a comparator that sorts double
values in reverse order.

Hi,
I'm trying to turn a double with decimal point
precision fifteen digits to the left into a sortable
String for Lucene (.346210426731253).
NumberTools is for longs so doesn't apply.
In Solr, NumberUtils.double2sortableStr prints

However, this doesn't happen. They are both scored the exact same.

Many thanks for your response, some good points which I had not thought of,
but unfortunately the problem remains.
To clarify my index sequence in pseudo-code is this:

}
createIndexWriter();

Yes, you can search while index writes are taking place, but
When you open an index reader, it essentially takes a snapshot
of the index and further modifications of the index are not visible to
that searcher as long as it's open. You must close and re-open the
reader (and associated searcher

I am currently writing a Lucene application and having a huge headache with

My requirements are that each time a file is indexed a search on its path is
performed to see if an update (delete then re-index) is required. If a
document with the same path exists then an IndexReader delet
