elasticsearch完全匹配

$params = array(
    "body" => array(
        "query" => array(
            "filtered" => array(
                "query" => array(
                    "match_phrase" => array(
                        "content"  => "破碎机磨粉机"
                    ),
                ),
            ),
        ),
    ),
);

这种匹配，搜索结果会同时包含 破碎机磨粉机 分词后的所有词,因此匹配比较严
