Improving Zend lucene search - general guidance?
Hi,
I have been using Java/lucene for a few years and it works well for me.
Recently we started to use PHP/lucene from Zend, I found some problems, especially
that for each query, it immediately loads whole term id/score (other info..) array into
memory, this would cause memory exhausion if there are many docs and query is based
on a common term.
I plan to improve PHP lucene query implementation based on Java lucene (I know Java
lucene code reasonably OK), but it seems that a lot of changes are needed, I would just
like a high level guidance: is this doable within a week, have other people already had similar
experiences?
Thanks very much for helps, Lisheng

Hi, Thanks very much for reply! Yes, PHP is stateless, just like
old CGI. All I can do is to get result efficiently within the
given query.
But we already got into PHP, I will see what the best I can do.
Best regards, Lisheng

PHP doesn't have java like "static" variables, right? They are "stateless".
All the information like term info that's loaded in the memory will be
gone for the next search.
You should use DBSight if you just have one week.
