Hi there. I have been working with semantic web type application for a while
and it appears to me pylucene could help me to get a much needed speed boost.
I have a couple of question to start.
My schema is fairly involved and has more than 100 elements. It would be
great to perform a search on any of these but how practical is that?
Should I be creating a summary type search using a smaller index of say 10 -
12 fields and then have detailed search based on a larger broader number of
fields in a different index. Any recommendations would be helpful. There is
no doubt I will have to create a query parser for my app.
Second questions is how can I get pydocs so I am aware of what functionality
exists and also syntax. I see examples in the samples folder but some
description of classes and methods is important. Is this available somewhere?
My last initial question has to do with sorting. I see that there are
advanced possibilities with the indexes to sort and filter. How advisable is
using sort for large record sets. For example, say you have got 20000 records
returned from your search. Because this will have a web interface I will only
be showing first 20 likely so it will be batching results. Is the sorting
filtering highly memory intensive?
These are all good questions best asked of the [email protected]
mailing list. PyLucene is a compilation of Java Lucene integrated with Python
via SWIG. The pylucene-dev mailing list can help you with python-specific
Lucene questions and bugs. For help about Lucene in general, please refer to
these sources:
- [email protected]
don't let the 'java' in the name of that list put you off, none of your
questions are java or python specific.
- [email protected]
for help in extending or adapting Java Lucene.
- the book 'Lucene in Action' written by Erik Hatcher and Otis Gospodnetic,
two of the Java Lucene developers. Most samples in this book were ported
to PyLucene and are in its 'samples/LuceneInAction' directory.
