如何在Sphinx中查询精确匹配的短语？

How to query Sphinx for an exact matching phrase?(如何在Sphinx中查询精确匹配的短语？)

问题描述

看起来Sphinx正在逐字搜索文档。我不知道如何在文档中搜索准确的短语。我试了SPH_MATCH_ALL，SPH_MATCH_PHRASE，但都是逐字搜索文档。我正在我的PHP应用程序中使用它。

如何查询Sphinx以匹配准确的字符串？

以下是我的代码：

$sphinx = new SphinxClient();
$mode = SPH_MATCH_PHRASE;
$sphinx->setServer('127.0.0.1', 9312);
$sphinx->setLimits(0,1);
$sphinx->setMaxQueryTime(5000);
$sphinx->setMatchMode($mode);
$sphinx->setFieldWeights(array('name' => 100));
$sphinx->setArrayResult(true);

$result = $sphinx->query('Lorem ipsum dolor sit amet, consectetur adipiscing elit.');
print_r($result);

返回结果如下：

Array (
    [error] =>
    [warning] =>
    [status] => 0
    [fields] => Array (
        [0] => name
        [1] => company
        [2] => image
        [3] => price
    )
    [attrs] => Array ()
    [total] => 0
    [total_found] => 0
    [time] => 0.000
    [words] => Array (
        [lorem] => Array (
            [docs] => 0
            [hits] => 0
        )
        [ipsum] => Array (
            [docs] => 0
            [hits] => 0
        )
        [dolor] => Array (
            [docs] => 0
            [hits] => 0
        )
        [sit] => Array (
            [docs] => 0
            [hits] => 0
        )
        [amet] => Array (
            [docs] => 0
            [hits] => 0
        )
        [consectetur] => Array (
            [docs] => 0
            [hits] => 0
        )
        [adipiscing] => Array (
            [docs] => 0
            [hits] => 0
        )
        [elit] => Array (
            [docs] => 0
            [hits] => 0
        )
    )
)

如您所见，Sphinx正在逐字搜索文档...

推荐答案

最佳方法是使用SPH_MATCH_EXTENDED2语法并将查询括在双引号中。

$sphinx->SetMatchMode(SPH_MATCH_EXTENDED2);
$sphinx->Query('"Lorem ipsum dolor"'); 

Extended syntax
