Index Entry Limit

The index entry limit is a configuration limit that can be used to control the maximum number of entries that is allowed to match any given index key (that is, the maximum size of an ID list). This provides a mechanism for limiting the performance impact for maintaining index keys that match a large percentage of the entries in the server. In cases where large ID lists might be required, performing an unindexed search can often be faster than one that is indexed.
