为什么 elasticsearch matchQuery 不返回结果？

Question

I have successfully indexed content with elasticsearch, but I am having troubles when trying to query content.

What I want to do is to search all docs that both contains value " ipsum " (in any of it's terms) AND term "type" should be equal to "cq:Page".

I am using High Level Rest Java Client. Tried with filtering and with Boolquery but it returns zero results.

Example:

SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
sourceBuilder.from(0);
sourceBuilder.size(10);

SearchRequest searchRequest = new SearchRequest();
searchRequest.indices("gettingstarted");
searchRequest.source(sourceBuilder);

BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();
                boolQueryBuilder.must(QueryBuilders.queryStringQuery("ipsum"));
boolQueryBuilder.must(QueryBuilders.matchQuery("type", "cq:Page"));
sourceBuilder.query(boolQueryBuilder);


SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);

Data looks like this:

{ 
   "took":4,
   "timed_out":false,
   "_shards":{ 
      "total":1,
      "successful":1,
      "skipped":0,
      "failed":0
   },
   "hits":{ 
      "total":{ 
         "value":1,
         "relation":"eq"
      },
      "max_score":1.0,
      "hits":[ 
         {

            "_score":1.0,
            "_source":{ 
               "docs":[

                     "sling:resourceType":"social/console/components/basepage",
                     "searchDescription":"Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sportsman delighted improving dashwoods gay instantly happiness six.

Related compact effects is on settled do.",
                     "pageImportanceRank":"4"
                  }, ...

Tried this also but without a success, it returns zero results.

boolQueryBuilder.must(QueryBuilders.matchQuery("type", NT_PAGE));

Answer 1

Maybe something like that:

GET index/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "multi_match": {
            "query": "ipsum",
            "fields": []
          }
        },
        {
          "match": {
            "type": "cq:Page"
          }
        }
      ]
    }
  }
}

"fields": [] -> meaning all fields

Answer 2

It worked with using matchPhraseQuery instead of matchQuery. My value was "cp:Page".

In this case matchQuery returns the document only if this term has exactly the same value as it is in it's index (and at the query time there are no analyzers used ).

On the other hand, matchPhraseQuery will use default analyzers at the query time as well so value in query will be the same as indexed value after analzsers change it.

Analyzers can be specified per-query, per-field or per-index. At index time, Elasticsearch will look for an analyzer in this order:

The analyzer defined in the field mapping. An analyzer named default in the index settings. The standard analyzer. At query time, there are a few more layers:

The analyzer defined in a full-text query. The search_analyzer defined in the field mapping. The analyzer defined in the field mapping. An analyzer named default_search in the index settings. An analyzer named default in the index settings. The standard analyzer.
