Complex Query System and Collections Schema for Typesense
TLDR Orion asks about the grammar for 'filter_by' search parameters and where to find a collections schema. Jason provides the needed documentation and encourages Orion to share back.

04:01 PMIs there a formal grammar for
filter_by or any of the search parameters? I am working on a complex query system which takes a query language, validates and parses it, then constructs typesense queries from the syntax tree. Doing this without knowing the precise filtering grammar (or other params) is quite a challenge. At the moment I've taken all the documented examples and tried to formalise them into PEG and BNF grammars but I would love to be more confident that it matches.Second (much more mundane) question, is there any way to programmatically get a collections schema? I'm using the schema to inject some more intelligent behaviour into the query system so that things like filtering
tags[] > 5 throws a useful syntax error in the frontend. I can copy-paste the schema when it changes but I would really love to avoid that.Orion
