ElasticsearchQueryGenerator

Create an org.elasticsearch.index.query.BoolQueryBuilder object from the com.google.gson.JsonElement object.

Library users can benefit from this BoolQueryBuilder object for convenient Elasticsearch query construction.

sample

String searchRequest = "{\"field\":\"user.name\",\"operator\":\"eq\",\"value\":\"shinwoosub\"}";
JsonElement json = (JsonElement) (new Gson()).fromJson(searchRequest, JsonElement.class);

// Create an `org.elasticsearch.index.query.BoolQueryBuilder` object from the `com.google.gson.JsonElement` object
BoolQueryBuilder boolQueryBuilder = generate(jsonElement);

SearchRequest searchRequest = this.index.createSearchRequest();
SearchSourceBuilder searchSourceBuilder = this.index.createSearchSourceBuilder().trackTotalHits(true)
        .query(boolQueryBuilder);

searchRequest.source(searchSourceBuilder);
SearchResponse response = restHighLevelClient.search(searchRequest, RequestOptions.DEFAULT);
