You can also try using a ConstantScoreRangeQuery in lieu of the plain RangeQuery. http://lucene.apache.org/java/docs/api/org/apache/lucene/search/ConstantScoreRangeQuery.html

Using this approach simplifies a lot the query you are suggesting (3). Gluing YYYY and MM in a field like YYYYMM also would make your query look nicer.

The solutions I have come across so far are: 1. Use the default QueryParser which will use RangeQuery which will expand into a number of Boolean clauses. It is quite likely that this will run into the TooManyClauses error. 2. Extend QueryParser and override getRangeQuery() and let it return a FilteredQuery containing a RangeFilter. 3. Split Dates during indexing into YYYY, MM, DD and create a custom RangeQuery that uses only the granularity needed: +date[20040830 TO 20060202] expands to (year:2004 AND month:08 AND day:30) OR (year:2004 AND month:08 AND day:31) OR (year:2004 AND month:09) OR (year:2004 AND month:10) OR (year:2004 AND month:11) OR (year:2004 AND month:12) OR (year:2005) OR (year:2006 AND month:01) OR (year:2006 AND month:02 AND day:01) OR (year:2006 AND month:02 AND day:02) Are there any other options, and which one is the best ? /B --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
