ajax - Elasticsearch:包含查询

Question

我的映射中有一列，其中包含一个字符串数组

col1
["asd","fgh","wer"]
["qwer","cvbvbn","popop"]
["cvbml","fhjhfrjk","fsdfd"]
["asd","trth","fdf"]

索引中未分析col列，我不想更改映射。

"col1":
{
    "type":"string",
    "index":"not_analyzed"
}

现在，我想检索出现字符串asd的所有记录。所以在这种情况下，我想要第一条和第四条记录。我尝试使用查询

        query: {

                    wildcard:{
                        "col1":"asd"
                    }
                }

与

POST localhost:9200/indexName/test/_search

但这给了我空洞的结果？在这种情况下，我应该使用哪个查询？

编辑

所以我能够解决上述问题。这是跟进。考虑这是我的数据

col1
["asd fd","fgh bn","wer kl"]
["qwer","cvbvbn","popop"]
["cvbml","fhjhfrjk wewe","fsdfd rtr"]
["asd","trth","fdf"]

所以现在，数组包含一些包含多个单词的字符串。现在，我仍然想返回第一和第四条记录。如果我采用我发布的解决方案，那么我只会得到第四个解决方案。如何将contains逻辑应用于col1中的数组的每个元素？

注意

部分解决方案是

{ "query": { "match_phrase_prefix": { "col1": "asd" } } }

同样，对于数据

col1
["asd fd","fgh bn","wer kl"]
["qwer","cvbvbn","popop"]
["cvbml","fhjhfrjk wewe","fsdfd rtr"]
["asd","trth","fdf"]

它返回第一条和第四条记录。但是，如果我有

col1
["fd asd","fgh bn","wer kl"]
["qwer","cvbvbn","popop"]
["cvbml","fhjhfrjk wewe","fsdfd rtr"]
["asd","trth","fdf"]

然后，它只再次返回第四个，这是现在可以理解的，asd不再是第一个记录中该值的前缀。

是否可以进行contains类型匹配，而不仅仅是前缀匹配？

Answer 1

您可以使用一个简单的term查询，它应该可以工作

POST localhost:9200/indexName/test/_search
{
    "query": {
        "terms": { "col1" : "asd" }
    }
}
