What is the best way to call Lucene from Python?

Hi what would be the best way to call Lucene from Python application? Is PyLucene really a good way for it? In particular: What about PyLucene's scalability? What about PyLucene vs Lucene performance? (this post is quite old: http://markmail.org/message/5pjbs7mdh4fpvsjb) best regards -- Valery

Hi Andi, > If you have any questions, feel free to ask this list. and here we go! :) I've benchmarked the StandardAnalyzer against a 3Mb text file. This test (se below) was executed both in PyLucene and in *plain* Lucene, i.e. in Java. The execution time in Java was 1.7 sec, whereas the PyLucen

Why 12 child threads in samples/ThreadIndexFiles.py ?

Hi all, Q1: Why 12 threads in samples/ThreadIndexFiles.py ? I have no idea how this example http://svn.apache.org/repos/asf/lucene/pylucene/trunk/samples/ThreadIndexFiles.py starts more than 1 thread: └─python,4922 ThreadIndexFiles.py ./corp ├─{python},4923 ├─{python},4924 ├─{

Re: Why 12 child threads in samples/ThreadIndexFiles.py ?

OK, initVM() immediately brings 11 child threads. So, we have 1 indexing thread. Now only Q3 is left: could someone please modify this example for indexing with more than 1 thread? best regards -- Valery A.Khamenya On Thu, Mar 25, 2010 at 11:19 AM, Valery Khamenya wrote: > Hi all, >

Slowdown during the search for similar documents

Hi, there is a strange slowdown during the search for similar documents. For some reason pylucene version is much slower than the pure Lucene one. The test document collection contains 200K docs. Here is the pylucene version: content = ref_doc.getField('content').stringValue() similarity_query =

Re: Slowdown during the search for similar documents

hm, during new runs we see only 2x slow down. So, no "much slower", but just "2x slower" -- both searches compared are done in single thread. best regards -- Valery A.Khamenya On Sun, Mar 28, 2010 at 2:09 PM, Valery Khamenya wrote: > yes, the same parameters. > &g

a Debian package of PyLucene 3 for Ubuntu 10.10 "Maverick" (AMD64) ?

Hi guys, I tried several times to install PyLucene 3 on Ubuntu 10.10 "Maverick" (AMD64). I have never succeeded with it (maybe 1 hour was never enough for it). Could someone, please, build a Debian package of PyLucene 3 for Debian 10.10? or alternatively write a clear guide on how to do it? If I

Re: [ANNOUNCE] Apache PyLucene 3.1.0

Thanks! btw, originally I went this way http://lucene.apache.org/pylucene/jcc/documentation/install.html , but it is not up-to-date and trunk doesn't seem to be compilable (problems with ant xml files, plus no doc directory etc). Then I used the tar and it worked like charm. best regards -- Vale
