Use Shared Constants For Query Building

Using shared constants in a single location will help to reduce duplication in the codebase. However, we must take care to keep efficiency up by avoiding the addition of more string concatenation.

Start by locating the query-building code and identifying duplicated query strings or fragments. Check how those values are currently assembled before deciding where shared constants belong. Done means the duplicated values are centralized without adding unnecessary string concatenation, with existing query behavior preserved.
