SphinxClient::setLimits — Set offset and limit of the result set

설명

public bool SphinxClient::setLimits ( int $offset , int $limit [, int $max_matches = 0 [, int $cutoff = 0 ]] )

Sets offset into server-side result set and amount of matches to return to client starting from that offset (limit). Can additionally control maximum server-side result set size for current query (max_matches) and the threshold amount of matches to stop searching at (cutoff).

인수

offset: Result set offset.
limit: Amount of matches to return.
max_matches: Controls how much matches searchd will keep in RAM while searching.
cutoff: Used for advanced performance control. It tells searchd to forcibly stop search query once cutoff matches have been found and processed.

반환값

the max_matches / cutoff parameters are priceless.



if you ever have a situation where you need a 'count' of the number of matches, but only need to display lets say the 'top 10', these 2 parameters are very handy.



we used to get the occasional 'unable to connect' error with sphinx, after implementing these 2 parameters where applicable, these issues disappeared, load dropped, and the servers were much happier.

I almost pulled out all my hair trying to figure this one out. After applying limits using



$s->setLimit(10,10); 



the search kept returning only false. getLastError() and getLastWarning() contained empty strings. 



The solution, like Nayana stated, is to add a positive non-zero integer $max to setLimit.

If you get an error 

per-query max_matches=0 out of bounds (per-server max_matches=1000).



make sure that you also set the $max to a value other than the default 0, 



there is an issue published with a patch if you feel like wanting to patch, 



the first option works well as a workaround.
