## Ranking modes

Constant | Description
SPH_RANK_PROXIMITY_BM25 | Default ranking mode which uses both proximity and BM25 ranking.
SPH_RANK_BM25 | Statistical ranking mode which uses BM25 ranking only (similar to most of other full-text engines). This mode is faster, but may result in worse quality on queries which contain more than 1 keyword.
SPH_RANK_NONE | Disables ranking. This mode is the fastest. It is essentially equivalent to boolean searching, a weight of 1 is assigned to all matches.
