Greetings everyone!

I’ve been working on some projects, one of them is going to be an open source platform for researchers to share pharmacokinetic data. The basics of the platform are done, now I’m thinking about the search mechanism.

I would like to write a system that enable researchers to compose queries, something like this. In that web a search string like this year>1998 year<2020 c:r t:cat or t:fish name:"Hippo" would give us this.

I was going to start writing something like that for my project, but then I realized that I might not been the first person with this kind of problem. That’s why I’m here, Do any of you know some library or pattern that would help me to implement this?

I did a basic search over internet and my results were scarce. Right now I think that it’s very specific and I would need to implement it by myself

Thanks!
