Doron Cohen commented on LUCENE-1540:
-------------------------------------
Thanks for reviewing Shai!
bq. Maybe instead of moving the unzip method to LuceneTestCase, you can put it
as a static method in _TestUtil? Also, _TestUtil already has a rmDir method, I
think we should use it? I would also do the same for fullTempDir.
Good point, will do.
bq. The method pathType(File f) in TrecDocParser – maybe instead of walking up
the path elements you can obtain its full absolute path (which is a String) and
then do indexOf() checks for the 4 types? It will simplify matters IMO.
Not sure yet if I like better this file separator sensitive approach, I'll take
a look.
bq. Typo in TDP: unmodofied --> unmodified.
Will fix.
bq. Maybe we can use String.replaceAll() which takes a regex? This is not
critical ...
Right, much simpler this way, will do!
bq. Does stripTags strips off tags of the HTML content? Or is it used for the
TREC types other than GOV2?
It strips any tags, but it is used by parsers which are not using the HTML
parser, that is, the Gov2 one does not use it.
bq. In TrecContentSource, can you replace TrecParserByPath.pathType to
TrecDocParser.pathType?
Good catch, this is part of older code, will do.
bq. Also, do we still need TrecParserByPath? I don't see that it's used.
Yes we do, this is an important addition of this patch - allowing you to index
trec docs of several formats. It is used, but dynamically, through the
algorithm in TrecContentSourceTest.testTrecFeedDirAllTypes(). So removing it
will not break compilation but will fail the tests.
> Improvements to contrib.benchmark for TREC collections

> Key: LUCENE-1540
> URL: https://issues.apache.org/jira/browse/LUCENE-1540
> Project: Lucene - Java
> Issue Type: Improvement
> Components: contrib/benchmark
> Reporter: Tim Armstrong
> Assignee: Doron Cohen
> Priority: Minor
> Fix For: 3.1, 4.0
>
> Attachments: LUCENE-1540.patch, LUCENE-1540.patch, LUCENE-1540.patch,
> trecdocs.zip

>
> The benchmarking utilities for TREC test collections (http://trec.nist.gov)
> are quite limited and do not support some of the variations in format of
> older TREC collections.
> I have been doing some benchmarking work with Lucene and have had to modify
> the package to support:
> * Older TREC document formats, which the current parser fails on due to
> missing document headers.
> * Variations in query format - newlines after <title> tag causing the query
> parser to get confused.
> * Ability to detect and read in uncompressed text collections
> * Storage of document numbers by default without storing full text.
> I can submit a patch if there is interest, although I will probably want to
> write unit tests for the new functionality first.
