TooManyClauses exception in Lucene (1.4)
Hi,
We're using queryparser to generate my queries (not ideal, and we're
planning on rewriting it, but at the moment we don't have the resources
to do so).
We have a default field "text" which contains all of our text fields,
and a "date" field which is just a string field in the format YYYY-MM-DD
(so we can sort).
I'm passing in the query string: broadband AND date:[2005-03-16 TO
2006-03-16]^0.01
(I'm weighting the date portion of the query so it doesn't affect the
sorting too heavily).
Running query.toString gives this: +text:broadband +date:[2005-03-16 TO
2006-03-16]^0.01
When I try to run the query, though, I get this Exception:
org.apache.lucene.search.BooleanQuery$TooManyClauses

at org.apache.lucene.search.Searcher.search(Searcher.java:33)
at org.apache.lucene.search.Searcher.search(Searcher.java:27)
I know Lucene 1.4 has a limited number of clauses, but assumed two or
three would be okay. :)
Any ideas would be gratefully received! Oddly, this doesn't seem to
occur every time, just with certain date ranges...
Cheers,
Tim.

Tim,
This is possible a lot of days:
date:[2005-03-16 TO 2006-03-16]
And if your 'date' field is more granular than 'a day', then this is a lot more hours/minutes/seconds/milliseconds.
Your range query is expanded to all unique values in the range. This is probably in the FAQ, but if not, look at the first snippet:
http://www.lucenebook.com/search?query=indexing+date+millisecond
If you don't need hours/minutes/seconds/milliseconds, don't index them.
