Java 使用 RestHighLevelClient 调用慢

直接使用 postman 调用 用时一秒

http://106.13.148.210:9200/_search { "query": { "match": { "book_id": { "query": 87, "operator": "OR", "prefix_length": 0, "max_expansions": 50, "fuzzy_transpositions": true, "lenient": false, "zero_terms_query": "NONE", "auto_generate_synonyms_phrase_query": true, "boost": 1 } } }, "size": 500 } 

使用 java 代码 8 秒多
