Question

我正在使用java执行ES查询：

query = 2bU: "70501" AND 2c2: <u>asasas</u>~

    SearchResponse response = client.prepareSearch("XYZ")
    .setTypes("MYTYPE")
    .setQuery(QueryBuilders.queryString(query))
    .setFrom((start-1)*.SEARCH_RESULT_PERPAGE).setSize(SEARCH_RESULT_PERPAGE)
    .execute()
    .actionGet();

    SearchHit[] results = response.getHits().getHits();

这个<u>asasas</u>的cos我得到了异常

Encountered: <EOF> after : "/u>~"]; nested: TokenMgrError[Lexical error at line 1,
column 37.  Encountered: <EOF> after : "/u>~"];

这是完整的例外

在这里查看保留字符的部分： http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html

在那里你可以发现/是一个需要转义的保留字符。请尝试以下方法：
