Sphinx结果不会在空格后返回匹配

Question

When trying to do a search for bmw motorrad or partials of it.

bmw is ok

bmw m or any characters after return no results

bmw motorrad returns the company

We finally got a chance to move our servers from managed to self managed. in the process we upgraded mysql from 5.0.37 to 5.5.28.

We also upgraded sphinx from 0.9.9 to 2.2.10 with Sphinx as a mysql engine. We are using Laravel 5.1 and using a package sngrl\SphinxSearch to connect to sphinx.

sphinxSearch search query

public function getQSAdvertiser($keyword){
    $sphinx = new SphinxSearch();
    $results = $sphinx
        ->search($keyword, 'companyqs')
        ->limit(10000)
        ->setMatchMode(\Sphinx\SphinxClient::SPH_MATCH_EXTENDED2)
        ->setRankingMode(\Sphinx\SphinxClient::SPH_RANK_MATCHANY)
        ->query();

    return $results;
}

Thanks for looking and appreciate any help.

Answer 1

You may need to change min_word_len to 1 to get single char matches.

But also 0.9 to 2.2 is a big jump! A number of defaults have changed. Mainly I think that old version may of had enable_star=0 as the default.

enable_star has been abolished as an option (and is effectively =1 always now)

So you need to add stars. Could do this in code. Change the query to 'bmw m*'

However there is expand_keywords=1 which gives you similar (but not identical) behaviour, will change rank slightly. That in theory would need no other code changes.
