Coreseek the total number of PHP search interface results and match number is not the same

Using Coreseek for full-text search, the results are as follows:

Array ([ERROR] = [WARNING] = [status] + 0 [fields] = = Array ([0] = content) [Attrs] = = Array () [matches] = = Array ([+] = array ([weight] = 1 [attrs] = = Array ()) [+] = array ([weight] = 1 [Attrs] = = Array ()) [+] = array ([weight] = 1 [attrs] = = Array ()) [+] = array ([weight] = = 1 [attrs] = = Array ()) [+] = array ([weight] = 1 [attrs] = = Array ()) [+] = array ([weight] =&G T 1 [attrs] = = Array ()) [[]] [[Weight] = Array ([attrs] = 1 [] = = Array ()) [[]] = array ([weight] =&gt ; 1 [attrs] = = Array ()) [+] = array ([weight] = 1 [attrs] = = Array ()) [[] = = Array ([weight] =&gt ; 1 [attrs] = = Array ()) [+] = array ([weight] = 1 [attrs] = = Array ()) [+] = array ([weight] =&gt ; 1 [attrs] = = Array ()) [+] = array ([weight] = 1 [attrs] + array ()) [[] = Array ([weight] =&gt ; 1 [attrs] =&GT Array ()) [+] + array ([weight] = 1 [attrs] = Array ()) [+] = array ([weight] = 1 [attrs] =&gt ; Array ()) [All] = Array ([weight] = 1 [attrs] = Array ()) [[] = = Array ([weight] = 1 [attrs] =&gt ; Array ()) [[Weight] = array ([weight] + 1 [attrs] = = Array ()) [[+] = [[]] = Array ([] = 1 [attrs] =&gt ; Array ())) [Total] = [Total_found] + 2931 [TIME] = 0.005 [words] = = Array ([i] = = Array ([docs ] = 2931 [hits] + 6974)))

Why is total 1000, but matches matches only 20 records?

Set _maxmatches value in sphinxapi.php

Client calls:
$CL = new Sphinxclient ();
$cl->setlimits (0, 500000);
