我有一个配方实体，它有一些标签（多对多映射），我想按标签搜索食谱。
这是我的食谱实体：
/**
* @ORM\Entity
* @ORM\Table(name="recipes")
* @ORM\HasLifecycleCallbacks
* @ExclusionPolicy("all")
*/
class Recipe
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
* @Expose
*/
protected $id;
/**
* @ORM\Column(type="string", length=150)
* @Expose
*/
protected $name;
...
/**
* @ORM\ManyToMany(targetEntity="RecipesTag", inversedBy="recipes")
* @ORM\JoinTable(name="bind_recipes_tags",
* joinColumns={@ORM\JoinColumn(name="tag_id", referencedColumnName="id")},
* inverseJoinColumns={@ORM\JoinColumn(name="recipe_id", referencedColumnName="id")}
* )
*/
private $tags;
这是我的配置：
fos_elastica:
clients:
default: { host: localhost, port: 9200 }
serializer:
callback_class: FOS\ElasticaBundle\Serializer\Callback
serializer: serializer
indexes:
td:
client: default
types:
Recipe:
mappings:
name: ~
ingredients:
type: "nested"
properties:
name: ~
tags:
type: "nested"
properties:
name: ~
id :
type : integer
categories:
type: "nested"
properties:
name: ~
id :
type : integer
persistence:
driver: orm # orm, mongodb, propel are available
model: ck\RecipesBundle\Entity\Recipe
repository: ck\RecipesBundle\Entity\RecipesRepository
provider: ~
listener: ~
finder: ~
然后我添加了一个自定义存储库来执行搜索：
public function filterFind($searchText)
{
$query_part = new \Elastica\Query\Bool();
$nested = new \Elastica\Query\Nested();
$nested->setQuery(new \Elastica\Query\Term(array('name' => array('value' => $searchText))));
$nested->setPath('tags');
$query_part->addShould($nested);
return $this->find($query_part);
}
然后我这样搜索：
$repositoryManager = $this->get('fos_elastica.manager.orm');
$repository = $repositoryManager->getRepository('ckRecipesBundle:Recipe');
$recipes = $repository->filterFind('mytag');
但是尽管有匹配的结果，但我没有得到任何结果。
我在谷歌上找不到任何答案。 有人可以帮帮我吗？

实际上，您忘了定义Filtered查询。
这应该有效：
public class CurrencyConverter extends Fragment {
public CurrencyConverter() {
}
TextView t;
public int to;
public int from;
public String[] val;
public String s;
String exResult;
public Handler handler;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.currency_converter, container, false);
t= (TextView) rootView.findViewById(R.id.textView4);
Spinner s1 = (Spinner) rootView.findViewById(R.id.spinner1);
Spinner s2 = (Spinner) rootView.findViewById(R.id.spinner2);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
this.getActivity(), R.array.name, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.select_dialog_singlechoice);
val = getResources().getStringArray(R.array.value);
s1.setAdapter(adapter);
s2.setAdapter(adapter);
s1.setOnItemSelectedListener(new spinOne(1));
s2.setOnItemSelectedListener(new spinOne(2));
Button b = (Button) rootView.findViewById(R.id.button1);
b.setOnClickListener(new View.OnClickListener() {
public void onClick(View View) {
if (from == to) {
Toast.makeText(getActivity().getApplicationContext(), "Invalid", 4000).show();
} else {
new calculate().execute();
}
}
});
return rootView;
}
public class calculate extends AsyncTask<String, String, String> {
@Override
protected void onPreExecute() {
super.onPreExecute();
}
@Override
protected String doInBackground(String... args) {
try {
s = getJson("http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.xchange%20where%20pair%20in%20(%22"+val[from]+val[to]+"%22)&format=json&diagnostics=true&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys&callback=");
JSONObject jObj;
jObj = new JSONObject(s);
exResult = jObj.getJSONObject("query").getJSONObject("results").getJSONObject("rate").getString("Rate");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return exResult;
}
@Override
protected void onPostExecute(String exResult) {
t.setText(exResult);
}
}
public String getJson(String url)throws IOException {
StringBuilder build = new StringBuilder();
HttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
HttpResponse response = client.execute(httpGet);
HttpEntity entity = response.getEntity();
InputStream content = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(content));
String con;
while ((con = reader.readLine()) != null) {
build.append(con);
}
return build.toString();
}
public class spinOne implements AdapterView.OnItemSelectedListener
{
int ide;
spinOne(int i)
{
ide =i;
}
public void onItemSelected(AdapterView<?> parent, View view,
int index, long id) {
if(ide == 1)
from = index;
else if(ide == 2)
to = index;
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
}
}

以下是响应方法。对我来说它有效。 http://obtao.com/blog/2014/04/elasticsearch-advanced-search-and-nested-objects/
基本上，您需要创建类似的查询：
{
"query":{
"filtered":{
"query":{
"query_string":{
"query":"*saf*"
}
},
"filter":{
"nested":{
"path":"categories",
"filter":{
"bool":{
"must": [{
"term":{
"categories.id":1
}
}]
}
},
"query":{
"match":{
"id":1
}
}
}
}
}
}
}
对我来说，PHP看起来像：
$bool = new Filter\Bool();
$bool->addMust(new Filter\Term(['categories.id' => $category->getId()]));
$nested = new Filter\Nested();
$nested->setPath("categories");
$nested->setFilter($bool);
$nested->setQuery($categoriesQuery);
$queryObj = new Query\Filtered($queryObj, $nested);
过滤器是Elastica \ Filter，Query是Elastica \ Query
