void mongo::FieldRangeOrSet::popOrClause ( const BSONObj & indexSpec = BSONObj() )

Removes the top or clause, which would have been recently scanned, and removes the field ranges it covers from all subsequent or clauses. As a side effect, this function may invalidate the return values of topFrs() calls made before this function was called.

Parameters:

indexSpec

- Keys of the index that was used to satisfy the last or clause. Used to determine the range of keys that were scanned. If empty we do not constrain the previous clause's ranges using index keys, which may reduce opportunities for range elimination.
