Elasticsearch match hyphen

Question

I need to match word like "1-2", however I am using standard analyzer which ignores "-",

• I cannot use "analyze_wildcard": true because it will return tokens like "1", "-", "2", which is not ideal solution.

• I cannot use third party plugin.

I am trying to set customized tokenizer by using regular expression, however none of them works.

Answer 1

I think the best way is to switch off the analyzer of your field, in which you want to match "1-2". Don't forget to use no analyzer on your search query.
