And then, in my fos elastica repository, i have this code :
$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);
I tried to put my query directly in a controller, but same result. I really don't know why my filter return no result.
Hope someone could help, cause i'm really don't see the answer

Answer 1

First thing to do is testing your query outside Elastica, you can get the JSON from the Sf2 Profiler or from the logs.
Next, make sure your documents are sent in Elasticsearch the way you want (perform a simple GET /youmiam/product/_search request to see them, in a tool like Sense).
I see that your brandLanguage field is using the standard analyzer, you can see how Elasticsearch index it with a query like this: GET /youmiam/_analyze?field=brandLanguage&text=FR - is there a token with the exact value fr? If not, there will be no match.
Best practice is to set this kind of field as "not_analyzed" too.
Beside that there is no issue with your code (you could use a FilteredQuery instead of postFilter but that's not the issue), you should look more closely at what is indexed and how to query it directly via Sense, and then translate it with Elastica.
