Subject [jira] Created: (LUCENE-1461) Cached filter for a single term field
Date Wed, 19 Nov 2008 01:13:44 GMT
Cached filter for a single term field

                 Key: LUCENE-1461
             Project: Lucene - Java
          Issue Type: New Feature
            Reporter: Tim Sturge

These classes implement inexpensive range filtering over a field containing a single term.
They do this by building an integer array of term numbers (storing the term->number mapping
in a TreeMap) and then implementing a fast integer comparison based DocSetIdIterator.

This code is currently being used to do age range filtering, but could also be used to do
other date filtering or in any application where there need to be multiple filters based on
the same single term field. I have an untested implementation of single term filtering and
have considered but not yet implemented term set filtering (useful for location based searches)
as well. 

The code here is fairly rough; it works but lacks javadocs and toString() and hashCode() methods
etc. I'm posting it here to discover if there is other interest in this feature; I don't mind
fixing it up but would hate to go to the effort if it's not going to make it into Lucene.
