RangeQueries expand to a boolean query containing all terms in the range, so it doesn't matter if you search on a course grain range, if you store the dates with high granulatiry -- the number of terms will be high.
this wiki page discusses some of the merrits of using multiple date fields with various levels of granulairty... http://wiki.apache.org/jakarta-lucene/LargeScaleDateRangeProcessing ...but frankly, i suggest you just use a ConstantScoringRangeQuery (which uses a RangeFilter under the covers) and save yourself the headache. : Date: Mon, 16 Oct 2006 13:43:33 -0400 : From: "Bushey, John" <[EMAIL PROTECTED]> : Reply-To: java-user@lucene.apache.org : To: java-user@lucene.apache.org : Subject: BooleanQuery.TooManyClauses exception : : Hi - Can someone explain the reason why I'm getting the TooManyClauses : exception? I have a general understanding of the issue based on my : reading, but I don't understand the mechanics of the it. Specifically : how is my query being expanded to cause this problem? How am I : exceeding the default 1024 clauses? My query looks like the following. : : : : pyLabel:(test) OR pyDescription:(test) AND ( pxCreateDateTime:[20060401 : TO 20060901] ) : : : : The problem only happens when my date range exceeds ~2 months. The date : is indexed with more precision, but for my query purposes I only care : about the date and not the time stamp portion. What can I do to solve : or mitigate this problem and be able to search a date range that spans : at least a year? Is setMaxClauseCount() a predictable solution? How : would reducing the precision of my date during indexing help? : : : : : : Thanks : : John : : : : : : : : -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
