Thanks, that does seem good in theory. I can get the field from each of the
terms and add them to a Set to de-dupe.
However, in practice queries of the following nature seems to fail with an
UnsupportedOperationException:
field:a*
field:[a TO b]

- and have some specific fields you want to show in a tag cloud?
A generic tag cloud of all terms will not be very helpful as all the
common words will dominate the tag cloud. What you want is to use some

Hi all,
Is there any relevance engine that is built in lucence and which can
be customized.

Both Solr or Lucene allow extensive customization of relevance
calculations. Examples include boosting matched in title field vs.
Body, or boosting recent documents more than older documents.

hi all,
I am new to Lucene. I am trying to use Lucene to generate
data for a document classifier. I need to generate wordno, lineno,
pageno for each term/phrase. I was able to use SpanQuery/SpanNearQuery
to get the wordno (span.start()) for the term/phrase. To get pageno
and lineno, a c
Hi,
I’m currently involved in a project of migrating from Lucene 2.9.1 to Solr
1.4.0.
During stress testing, I encountered this performance problem:
While actual search times in our shards (which are now running Solr) have
not changed, the total time it takes for a query has increased dramatic
H. Assuming you called rewrite, I'm going to have to defer
that one, I'm not familiar enough with how range queries operate.
But what version of Lucene are you using?
Sorry I can't be more help

No, you can't do this with any existing analyzers I know of. Part
of the problem here is that there's no good generic way to KNOW
what a page and line are.
Have you investigated payloads? I'm not sure that's a good fit for
this particular problem, but it might be worth investigating.

Hi
Apologies for re sending this email but I was just wondering if any one might
be able to advise on the below. I'm not sure if I've provided enough info.
Again any help would be appreciated.

Can you post the full exception? And also the log output from
IndexWriter.setInfoStream.

Is this an "apples to apples" comparison? That is, are you measuring
the same complete flow on both apps? Does the Lucene app return fields
via HTTP?

Because that was so slow I just wrote a utility class to create a list of N
IndexWriters and round robin documents to them as the index is created. Then we

Somewhat embarrassingly I can't seem to reproduce the problem anymore! I've
tried to reproduce it for the last hour now and no luck. Sorry about that. If
it happens again then I'll post back to the list.
Thanks for your time.

thanks DC for the boosting info.. can i plz have some code pointers to the same.
As far as i understand the boosting is done during harvesting of the documents.
Thats is fine but how do i achieve dynamic boosting...For example I wish to
