Hi
I'm indexing 4 .txt files using:
-Lucene (lucene-core-4.9.0.jar)
-BrazilianAnalyzer (lucene-analyzers-common-4.9.0.jar)
The files have the following content:
- File A: tecnológico
- File B: tecnologico
- File C: tecnologias
- File D: tecnolo
For the search used as well:
- Lucene (lucene-core-
Hey Vishnu, I'm trying to understand what you're trying to accomplish
(cc'ing Lucene user group to solicit additional advice)
Are you trying to extract all the terms for a given document? If so, you
might just want to enable term vectors to analyze the index terms for the
document.

Phew... thanks for bringing closure! And, good sleuthing.

* I'll check the documentation for MatchAllDocsQuery.
* I'm already changing my code to create BooleanQueries instead of filters -
is that better than MatchAllDocsQuery or it's the same?
* Is using MatchAllDocsQuery the only way to disable scoring?
* Would you have any good

Hi
First you can use MatchAllDocsQuery, which matches all documents. It will
save a HUGE posting list (TAG:TAG), and performs much faster. For example
TAG:TAG computes a score for each doc, even though you don't need it.
MatchAllDocsQuery doesn't.
Second, move away from Hits ! :) Use Collectors i
Hi,
we use Lucene to store around 300 millions of records. We use the index both
for conventional searching, but also for all the system's data - we replaced
MySQL with Lucene because it was simply not working at all with MySQL due to
the amount or records. Our problem is that we have HUGE perform
