我尝试按语言过滤弹性查询。我的查询工作正常，但是当我添加过滤器时，我得到0结果。

然后，在我的fos elastica存储库中，我有这个代码：
$boolQuery = new \Elastica\Query\Bool();
$query = new \Elastica\Query;
$queryString = new \Elastica\Query\QueryString();
$queryString->setQuery($searchText);
$queryString->setAnalyzer('classic_analyser');
$queryString->setFields(array('product.name', 'product.brand', 'product.ingredient'));
$boolQuery->addMust($queryString);
$query->setQuery($boolQuery);
$filter = new \Elastica\Filter\Term();
$filter->setTerm('brandLanguage', 'fr');
$query->setPostFilter($filter);
return $this->find($query);
我试图将我的查询直接放在控制器中，但结果相同。我真的不知道为什么我的过滤器没有返回结果。
希望有人可以提供帮助，因为我真的没有看到答案
答案 0 :(得分：2)
首先要做的是在Elastica之外测试您的查询，您可以从Sf2 Profiler或日志中获取JSON。
接下来，确保您的文档以您希望的方式在Elasticsearch中发送（在工具like Sense中执行简单的GET /youmiam/product/_search请求以查看它们。）
我看到您的brandLanguage字段正在使用标准分析器，您可以看到Elasticsearch如何使用以下查询对其进行索引：GET /youmiam/_analyze?field=brandLanguage&text=FR - 是否存在具有确切值{{1}的标记}？如果没有，就没有匹配。
最佳做法是将此类字段设置为“not_analyzed”。
除了您的代码没有问题（您可以使用FilteredQuery而不是postFilter，但这不是问题），您应该更仔细地查看索引的内容以及如何通过Sense直接查询，然后翻译它与Elastica。
