Class: Card::Content::Chunk::QueryReference

Inherits:
Reference show all
Defined in:
mod/core/chunk/query_reference.rb

Overview

This should find +Alfred+ in expressions like 1) "name":"Alfred" 2a) "name":["in","Alfred"] 3a) "plus_right":["Alfred"] but not in 2b) "content":"foo", "Alfred":"bar" 3b) "Toni"] ("Alfred" is an operator here) It's not possible to distinguish between 2a) and 2b) or 3a) and 3b) with a simple regex, hence we use a too general regex and check for query keywords after the match, which of course means that we don't find references with query keywords as name
