弹性搜索错误 - [prefix] 查询不支持 [prefix]

Question

当我发布以下查询时，我收到了错误响应

{"error":{"root_cause":[{"type":"parsing_exception","reason":"[prefix] query does not support [prefix]","line":1,"col":119}],"type":"parsing_exception","reason":"[prefix] query does not support [prefix]","line":1,"col":119},"status":400}

这是我的 POST 查询：

{"from":0,"size":10,"sort":{"_score":"desc"},"query":{"bool":{"must":{"bool":{"should":[[{"prefix":{"title":{"prefix":"of","boost":"1.0"}}}],{"multi_match":{"query":"of","fields":["title^1.0"]}},{"query_string":{"query":"(\"of\")","fields":["title^1.0"]}}]}}}}}

如何使此查询适用于我的自动完成搜索？

Answer 1

prefix 命令接受“值”而不是“前缀”。 此外，“boost”值是数字类型，因此不应将其括在引号中。

所以应该是：

{"prefix":{"title":{"value":"of","boost":1.0}}}

代替：

{"prefix":{"title":{"prefix":"of","boost":"1.0"}}}
