Allow searching or filtering backlink blocks within a specific object

I use Projects as ongoing contexts (for example, a property called “7044”). Meeting notes and Daily Notes contain individual blocks that I link to the 7044 Project. The Backlinks section on 7044 does a good job of bringing those blocks together.

I would like to be able to search or filter those backlink blocks by keyword. For example, if 7044 has years of backlinks covering leasing, roofs, HVAC, parking, capital projects, etc., I want to open 7044 and search its backlinks for “roof.”

The desired result would be:

Project 7044 + keyword “roof” → only backlink blocks related to 7044 that contain “roof.”

Currently, Extended Search can find all blocks containing “roof,” and a Project can show all blocks backlinked to 7044, but there does not appear to be a way to combine those two conditions at the block level. Find in Page also does not search the backlink content displayed on the Project page.

This would be especially useful for projects or other objects that accumulate a large backlink history over time, without requiring users to anticipate every future search and manually tag or categorize each block.
