[Value] JET_bitSeekLE [Meaning] 
The cursor will be positioned at the index entry closest to the end of the index that is less than or equal to an index entry that would exactly match the search criteria. The end of the index is the index entry that is found when moving to the last record in that index. The end of the index is not the same as the high end of the index, which can change depending on the sort order of the key columns in the index. It is not meaningful to use this option with a search key that was constructed using JetMakeKey using a wildcard option intended to find index entries closest to the start of the index.
