ElasticSearchTemplate下进行查询，数据存在但返回结果为空

我将相同的查询语句放到kibana的console里查询，数据返回了正常结果。语句如下：
GET /txn/_search
{
"query": {
"multi_match" : {
"query" : "兰",
"fields" : [
"cName^1.0",
"commonname^1.0",
"name^1.0"
],
"type" : "best_fields",
"operator" : "OR",
"slop" : 0,
"prefix_length" : 0,
"max_expansions" : 50,
"zero_terms_query" : "NONE",
"auto_generate_synonyms_phrase_query" : true,
"fuzzy_transpositions" : true,
"boost" : 1.0
}
}
}
不知是什么原因，请老哥们帮着看看。
