在Azure搜索中使用Lucene模糊搜索和同义词 [英] using lucene fuzzy search and synonyms with Azure Search

问题描述

我希望能够同时处理模糊搜索和同义词.我尝试了几种方法，但无法正常工作.

I want to be able to handle fuzzy search, as well as synonyms at the same time. I tried it in a several ways, but I cannot get it working.

我的索引中包含以下值:

I have these values in my index:

white
black
light
dark

和这个同义词规则:

white,light
black,dark

如果我执行查询 queryType = full& search = light 或 queryType = full& search = white ，它将始终返回light和white值.所以同义词起作用了.

If I perform the query queryType=full&search=light or queryType=full&search=white, it always returns both values, light and white. So synonyms are working.

如果我执行查询 queryType = full& search = light〜1 ，那么只会返回light.但是白色在哪里?

If I perform the query queryType=full&search=light~1, then only light will be returned. But where is white?

模糊搜索和同义词的结合尚不可行，还是我做错了什么?

Is the combination of fuzzy search and synonyms not possible yet, or am I doing something wrong?

推荐答案

同义词扩展不适用于通配符搜索词；前缀，模糊和正则表达式项不会扩展.

Synonym expansions do not apply to wildcard search terms; prefix, fuzzy, and regex terms aren't expanded.

如果您需要执行一个应用同义词扩展和通配符，正则表达式或模糊搜索的查询，则可以使用 OR 语法组合查询.

If you need to do a single query that applies synonym expansion and wildcard, regex, or fuzzy searches, you can combine the queries using the OR syntax.

例如，要将同义词与模糊搜索结合使用，您将需要进行如下查询:

For example, to combine synonyms with fuzzy search you would need to have query like this:

search=light~1|light

或

queryType=full&search=light OR light~1

如果您使用的是Lucene查询语法

if you're using Lucene query syntax
