elasticsearch - 使用双引号搜索关键字以在elasticsearch中获得完全匹配

Question

如果用户通过在关键字周围加上引号进行搜索，例如“flowers and mulch”，则应显示完全匹配项。

我尝试使用 query_string，它几乎可以工作，但对这些结果不满意。

谁能帮帮我。

{
    "query": {
        "query_string": {
           "fields": ["body"], 
           "query": "\"flowers and mulch\""
        }
    }
}

Answer 1

您应该使用 phrase_match 来精确匹配短语:

{
    "query": {
        "match_phrase": {
            "body": "flowers and mulch"
        }
    }
}

Phrase matching

In the same way that the match query is the “go-to” query for standard full text search, the match_phrase query is the one you should reach for when you want to find words that are near to each other.
