Did a google serach on the problem when using the range search phrase of
"+datefield:[199801 TO 200512]" (date stored as "YYYYMMDD") which
returns 1 million hits.
error: org.apache.lucene.search.BooleanQuery$TooManyClauses
Adding "-Dorg.apache.lucene.maxClauseCount=2400" to java option allowed
the search query to run without error. The actual value needed is
between 2300 and 2400. At 2300 the query fails.
My question is how does Lucene perform range query? As a bunch of
smaller boolean queries? How does one estimate the number of clauses
required for a general query and more specifically on a range query?
Thanks.
