我的弹性搜索查询为:
{
"query": {
"bool": {
"must": [
{
"match": {"title": "accountant"}
},
{
"nested": {
"path": "schools",
"query": {
"bool": {
"must": [
{ "match": { "schools.school_name": "Duke University" }}
]
}}}}
]
}}}
我正在使用php的Elastica库,我想将此原始查询转换为Elastica。我知道我可以从Elastica运行原始查询,但我更喜欢使用Elastica类。我尝试过this和this。但它们都不起作用。这是我当前代码的简化版本:
$schoolsTermFilter = new \Elastica\Filter\Term(['schools.school_name' => "Duke University"]);
$schoolsBoolFilter = new \Elastica\Filter\Bool();
$schoolsBoolFilter->addMust($schoolsTermFilter);
$nestedFilter = new \Elastica\Filter\Nested();
$nestedFilter->setPath("schools");
$nestedFilter->setFilter($schoolsBoolFilter);
$boolFilter = new \Elastica\Filter\Bool();
$boolFilter->addMust($nestedFilter);
$query->setPostFilter($boolFilter);
但是,这会返回空结果。原始查询确实返回结果,所以我知道我应该得到一些东西。有人可以帮助我吗?感谢

这是QueryBuilder版本(> = v1.4.2.0):
$qb = new \Elastica\QueryBuilder();
$query = new \Elastica\Query(
$qb->query()->bool()
->addMust($qb->query()->match(
'title',
'accountant'
))
->addMust($qb->query()->nested()
->setPath('schools')
->setQuery(
$qb->query()->bool()
->addMust($qb->query()->match(
'schools.school_name',
'Duke University'
))
)
)
);

以下是Elastica的1:1翻译供您查询:
$query = new \Elastica\Query();
$matchQuery = new \Elastica\Query\Match();
$matchQuery->setField("title", "accountant");
$schoolsTermQuery = new \Elastica\Query\Match();
$schoolsTermQuery->setField("schools.school_name", "Duke University");
$schoolsBoolQuery = new \Elastica\Query\Bool();
$schoolsBoolQuery->addMust($schoolsTermQuery);
$nestedQuery = new \Elastica\Query\Nested();
$nestedQuery->setPath("schools");
$nestedQuery->setQuery($schoolsBoolQuery);
$boolQuery = new \Elastica\Query\Bool();
$boolQuery->addMust($matchQuery);
$boolQuery->addMust($nestedQuery);
$query->setQuery($boolQuery);
print_r(json_encode($query->toArray()));
您粘贴的Elasticsearch查询不包含过滤器,仅包含查询。因此,Elastica翻译不应使用来自\Elastica\Filter
但来自\Elastica\Query
的对象。此外,如果要在Elasticsearch中使用之前验证查询,可以使用$query->toArray()
进行打印。
