I am using RestHighLevelClient method connection es, I query part of the core code
SearchSourceBuilder sourceBuilder=new SearchSourceBuilder ();

//query condition
//create BoolQueryBuilder object
BoolQueryBuilder BoolQueryBuilder=new BoolQueryBuilder ();

//under the matching index of all field participle query
QueryStringQueryBuilder criteriabuilder=QueryBuilders
QueryStringQuery (inputValue. GetValue ());
//configuration hanlp participles,
Criteriabuilder. Analyzer (" hanlp - index ");

Criteriabuilder. UseDisMax (true);

//child boolQueryBuilder condition condition, used to represent the query conditions or the relationship between the
BoolQueryBuilder childBoolQueryBuilder=new BoolQueryBuilder ()
Should (criteriabuilder);
//query condition is added to the boolQueryBuilder
BoolQueryBuilder. Must (childBoolQueryBuilder);

SourceBuilder. Query (boolQueryBuilder);
//how much each page article data
SourceBuilder. Size (10000);


//add highlighting
//sourceBuilder. Highlighter (highlightBuilder);

//add the request body into the request
The searchRequest. Source (sourceBuilder);

//set the timeout
The searchRequest. Scroll (TimeValue timeValueMinutes (1 l));

//3, send the request
The SearchResponse the SearchResponse;

The searchResponse=esc. Client. The search (searchRequest);
//System. Out. Println (the searchResponse. ToString ());

//processing search accuracy document the results
SearchHits hits.=the searchResponse getHits ();

//retrieve the number of hit
Long totalHits=hits. GetTotalHits ();


Float maxScore=hits. GetMaxScore ();

//get scrollID
String scrollId=the searchResponse. GetScrollId ();
System. Out.println (" scrollId - & gt;" + scrollId);


SearchHit [] searchHits=hits. GetHits ();

//get data matching, total
For (SearchHit hit: searchHits) {
//take _source field values
String sourceAsString=hit. GetSourceAsString ();//take into a json string
//sourList. Add (sourceAsString);
//sourList. Add (scrollId);
}
I have been here for the total number of data in a match, every time I want to take 20 article, click the next page, article 20 after the query out

CodePudding user response:

Every time take 20 hit, my idea is to take hitString cycle, on the list, and then return

Pseudo code:

 
Int limit=0; 
For (SearchHit hit: hits. GetHits ()) {
If (limit==page) {
break; 
} 
String hitString=hit. GetSourceAsString (); 
List. The add (hitString); 
//here take index 1-20 
Limit++; 

}

The building Lord, how to write ah, now have the answer? I also met this problem
