FilderQuery与Solarium的析取

Question

我最近在使用PHP/Solarium时偶然发现了Solr的一个奇怪的行为。

我为一个filterQuery构造了一个查询，并像这样构建它：

$select = array(
        'query'     => $this->getSearchTermForQuery(),
        'fields'    => '*,score',
        'start'     => $this->numResultsPerPage * ($this->currentPage-1),
        'rows'      => $this->numResultsPerPage,
        'component' => array(
            'edismax' => array(
                'queryfields' => implode(' ', array(
                    $this->queryFields['firstArray'],
                    $this->queryFields['secondArray'],
                    $this->queryFields['thirdArray'],
                )),
            ),
        ),
        'sort' => $this->orderBy,
    );

方法"getSearchTermForQuery()“构建发送到Solr服务器的字符串。它完美地处理了单个单词或组合，如“夏天和冬天”。现在我想实现一个析取，如果它是用户输入中显式需要的。所以会有一个类似于“夏天或冬天”的字符串。这个也很好用。现在如果我得到像“(夏季和冬季)或冬季”这样的东西，事情就变得复杂了。在这种情况下，我得到了一个非常奇怪的结果。

再次编辑Hello，我的旧示例已经不再有意义了，所以我删除了它们。我目前所处的状态最好用以下几点来解释。

我想我现在离问题更近了。在当前状态下，我使用的是edismax queryparser。我的查询如下所示：

#queryString: "((+"Test"+"Sommer")(+"Test"))"

使用少量的查询字段，一切似乎都能正常工作，解析后的查询如下所示：

#parsedQuery: "(+((+DisjunctionMaxQuery((content:test | daad_imperia_title:test)) +DisjunctionMaxQuery((content:somm | daad_imperia_title:somm))) (+DisjunctionMaxQuery((content:test | daad_imperia_title:test)))))/no_coord"

这会产生预期的结果/行为。但是，如果我使用所有的查询字段，我希望解析后的查询的结构发生变化。它看起来是这样的：

它只创建一个包含查询中所有单词的大dismaxQuery。有人知道吗？我想我快疯了。

我希望有人能在这方面给我一个提示。

致以最好的问候，罗纳德

免责声明:我是Solr Query Debugger谷歌浏览器插件的作者。

这主要取决于集合是如何配置的，以及您使用的是哪种查询解析器(我假设是edismax)。

如果您可以跟踪Solr实例的日志文件，这将有助于您提交真正的查询。

这样，您就可以在浏览器中使用该查询，然后对其进行调试。

实际上，我建议使用调试器来查看正在执行的是什么，并解释为什么您的查询具有如此奇怪的行为。

还有其他调试器：

• splainer.io - by OpenSource Connections team
• Solr Explain

因此，只需在浏览器中执行Solr查询，如果它可以工作，则启动您喜欢的Solr调试器。

在我的插件页面中，你会看到Debug和Echo标签页，它们解释了Solr执行了什么。在Explain选项卡中，您将看到以树形式组织的乐谱解释。

希望这能有所帮助。
