Persistent sphinx connector for NodeJs

This repository is a fork of the unmantained limestone with some changes to fix bugs and specially to make the persistent connection work. It adds a method persConnect to force a persistent connection. ES6 Required

Here is an example of opening a persistent connection and running multiple queries in an interval:

var limestone = require("./limestone").SphinxClient();

llimestone.persConnect(9312).then( function(limestone) {
        console.log('Connected, sending queries');

        setInterval(() => {
            limestone.query({
                    'query' : 'dog', // query object with sphinx options
                    'maxmatches' : 70,
                    'limit': 70,
                    filters: [
                        {
                            attr: 'oneFilter',
                            values: [12]
                        },
                    ],
                    'indexes':'myindex, myotherindex'},
                function(err, answer) {          // callback
                    console.log('Extended search yielded ' +
                        answer.match_count + " results\n" +
                        JSON.stringify(answer));
                   

                });
        }, 1000);
    }).reject((e) => {
        console.log('Connection error: ' + err.message);
        process.exit();
    });
