Hi
I got it working before I saw your latest mail, the only problem is
that it doesn't look very efficient. This is my duplicate method, the
problem is that I have to enumerate through *every* term. This was worse
before because I was only interested
in terms that matched a particular field (
Here's an excerpt from something I wrote to enumerate all the terms for a
field. I hacked out some of my tracing, so it may not even compile .
Basically, change the line "if (td.next())" to "while (td.next())" and every
time you stay in that loop for more than one cycle, you'll have duplicate
Hi,

Sure, you can use the TermDocs/TermEnum classes. Basically, for a term
(probably column value in your app) these let you quickly answer the
question "which (and how many) documents does this term appear in". What you
get is the Lucene doc id, which let's you fetch all the information about
the doc
