如何在 sphinxapi 节点模块上设置选项？

Question

我正在使用节点的 node-sphinx 模块并让它工作，但我能弄清楚的是如何设置属性。查看示例代码后：

var SphinxClient = require ("sphinxapi"),
    util = require('util'),
    assert = require('assert');

var cl = new SphinxClient();
cl.SetServer('localhost', 19312);

我想你只是使用了：

cl.SetRankingMode(ranker, rankexpr);
cl.SetSortMode(mode, clause);
cl.SetFilter(attribute, values, exclude);
etc...

但不确定需要什么，字符串、整数、什么值或常量，如 php 连接器等

是否有使用此模块的示例？

编辑

我能够像下面这样设置这些属性：

cl.SetMatchMode(SphinxClient.SPH_MATCH_EXTENDED2);
cl.SetRankingMode(SphinxClient.SPH_RANK_SPH04);
cl.SetFieldWeights({ 'text': 100, 'tags': 200});

设置字段权重中的文本和标签是我索引中数据库中的字段。
