Match only the same tokens

Elastic Stack Elasticsearch
1

Hi,

I have this situation: I want to get documents that have the same tokens as my query. Not documents that can have more tokens that my query as match_phrase does.
I can't use term because I need to consider also synonyms and stopwords and also I have to ignore the position of tokens

Example:
brown fox matches brown fox
brown fox matches fox brown
brown fox doesn't match brown fox and dog

Can you help me with this issue?

Thank you.

Maybe thefingerprint token filter is what you need. It de-dups tokens though so brown fox would match fox brown brown

Thank you a lot Mark,
I will try this token.
