The java-high-level-rest-client provides a method to search on elasticsearch using a term that Shown below its code
SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
sourceBuilder.query(QueryBuilders.termQuery("user", "kimchy"));
But I want to do a query on multiple fields like this: "user"="kimchy" and/or "city"="london".
I see the multi-search query and multi-match query but they don't do what I want.
Thanks for the help!!
try this:
BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();
boolQueryBuilder
.filter(QueryBuilders.termQuery("user", "kimchy"))
.filter(QueryBuilders.termQuery("city", "london"));
SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
sourceBuilder.query(boolQueryBuilder);
the filter/must/should method on BoolQueryBuilder, depends on which context you want, if you want "or", you can use should.
One can try this.
BooleanQuery.Builder booleanQuery = new BooleanQuery.Builder();
foreach (var term in (s + ',' + t).Split(','))
{
booleanQuery.add(new TermQuery(new Term("content", term)), BooleanClause.Occur.SHOULD);
}
//booleanQuery.add(new TermQuery(new Term("content", s)), BooleanClause.Occur.MUST);
//booleanQuery.add(new TermQuery(new Term("content", t)), BooleanClause.Occur.MUST);
TopDocs hits = searcher.search(booleanQuery.build(), int.MaxValue);
