[fw-general] Sorting with Zend Lucene

[Matt Schraeder]

I'm having a rather drastic ussing with sorting using Zend Search
Lucene.  Our index has 18,000 documents, so light as far as Lucene is
concerned.  I can perform a search that will pull back all of our
records with no problem.
 
However, once I attempt to add a sort field (Sorting by Title for
instance), the script crashes with an out of memory exception.  What is
the best way to handle sorting to avoid running out of memory?
