如何使用Elasticsearch Java API执行以下查询？

Question

I am using spring data elasticsearch, I want to be able to perform the following search query on my index "fruits" of type "fruit":

{
   'sort': {'fruitid': 'desc'}, 
   'query': {
      'query_string': {
         'query': u'Banana AND (start:>=1492274000000) AND (end:<=1386842400000)'
      }
   }, 
   'facets': {
      'fruit_color': {
          'terms': {'field': 'fruit_color', 'size': 5}
      }, 
      'fruit_weight': {
          'terms': {'field': 'fruit_weight', 'size': 5}
      }
}

How do I do this with the Java API? Note I do not want to use any model class.

The Java code below shows you how to create two TermFacetRequest for the fruit color and weight and how to add them to your query by calling withFacet() . It also shows you how to add the query_string query using the QueryBuilders.queryStringQuery() method call.

// create the fruit color facet
TermFacetRequest fruitColor = new TermFacetRequest("fruit_color");
fruitColor.setFields("fruit_color");
fruitColor.setSize(5);

// create the fruit weight facet
TermFacetRequest fruitWeight = new TermFacetRequest("fruit_weight");
fruitWeight.setFields("fruit_weight");
fruitWeight.setSize(5);

SearchQuery searchQuery = new NativeSearchQueryBuilder()
    .withPageable(new PageRequest(0, 10))
    .withQuery(QueryBuilders.queryStringQuery("Banana AND (start:>=1492274000000) AND (end:<=1386842400000)"))                
    .withSort(SortBuilders.fieldSort("fruitId").order(SortOrder.DESC))                
    .withIndices("fruit").withTypes("fruit")
    .withFacet(fruitColor)            <--- add the fruit color facet
    .withFacet(fruitWeight);          <--- add the fruit weight facet
