SphinxClient::setRankingMode — Set ranking mode
Sets ranking mode. Only available in SPH_MATCH_EXTENDED2 matching mode.
|Default ranking mode which uses both proximity and BM25 ranking.
|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.
|Disables ranking. This mode is the fastest. It is essentially equivalent to boolean searching, a weight of 1 is assigned to all matches.
Returns TRUE on success or FALSE on failure.
