             Summary: complex Query cause luene outMemory
                 Key: LUCENE-5917
                 URL: https://issues.apache.org/jira/browse/LUCENE-5917
             Project: Lucene - Core
          Issue Type: Bug
          Components: core/search
    Affects Versions: 4.9
         Environment: 128G RAM  + 1.5T SSD + 1.2T DATA(10*10000*10000 records).

            Reporter: Littlestar
            Priority: Minor


RangeQuery, prefixQuery and WildcardQuery use FixedBitSet when TERM_COUNT >= 
350 or DOC_COUNT_PERCENT >=0.1.
It use a lots of memory when maxDoc very large.

MultiTermQueryWrapperFilter<Q extends MultiTermQuery> extends Filter

a little threads run with query "a* OR b* OR c*.....OR z*“ will cause luene 
outMemory, but there is no ways to prevent it.

another thing, some complex query also use a lot of memory too..


I think query implements Accountable(#ramSizeInBytes), users can throw a 
exception better than OutOfMemory.
