Earlier versions of InDesign included a “Search: Selected” option in Find/Change.
This made it possible to safely replace text only within a selected area or page.

In current versions, this option has been removed, and Search: Document ignores selections entirely, making page-specific replacements impossible when text exists in multiple, unthreaded text frames.

This is a serious regression for production and packaging design workflows, where the same value (order number, batch number, SKU) appears multiple times per page and must be changed per page only.

Please restore Search: Selected, or introduce a Search: Page scope in Find/Change.
