How to search using keywords or tags?

Hello everyone, I need help to resolve a question regarding Elasticsearch.

I want to use the tags but in a different way. I am using the following composition when making the "tags":

#RGB keyboard

Is it possible to do a search for a product using this type of specific tags, I mean to remove the symbol # to read the string and thus make a match?

I hope I am not confusing you with my question.

Thank you.
