Just checking out some alternatives to the Phalcon model binding library for edge cases like my apps search and listing functionality (which would be nearly impossible to move to Phalcon), and found something that has a pretty cool syntax for grouped where clauses https://github.com/usmanhalalit/pixie#grouped-where and subqueries https://github.com/usmanhalalit/pixie#sub-queries-and-nested-queries. Have I missed a large part of the docs, or is this something Phalcon would rather I used another project for if I require?
