Hi. I've read a few things about paging functionality for the searcher. I
have already rolled my own in the meantime for batching and paging but still
wondering if this functionality already exists somewhere that I am just
unaware of. I am providing a start position and calculating an end position
for xrange based on hits.length() to keep the end position within the range
of results. In any case, I read:
Hits hits = searcher.search(query, new PageFilter(1,20));
In another, this version:
hits = searcher.search(query, 0, 10);
I could not locate a PageFilter method in the java docs and the second method
throws an exception.
I'm not sure I understand your question exactly but there is no class called
PageFilter in the Java Lucene code base. Hence there is no such class in
PyLucene either. If you wrote your own PageFilter in Java and are wondering
about how to integrate it into PyLucene, you can actually write in python by
creating a class with a method named 'bits' taking an IndexReader instance and
returning a Java BitSet instance (exported by PyLucene), as is done, for
example, in the test_FilteredQuery.py unit test.
This is somewhat documented in the README file under 'Extending Java Lucene
classes from Python'.
Andi..
