I created a DSL parser and compiler for integrating search in Web and Node.js apps.

Take a look at my latest article describing how to use the @quenk/search-filters DSL to generate database queries from user input. Example uses mongodb.

I have been using prior versions of it in past projects and it helped me keep search under control. Still have some features I would like to introduce like supporting $not and $exists but it's serving its purpose for the projects I'm working on now.

If you have any questions or want help using it, feel free to reach out!
