Child-block preview in the search panel (while using keywords from father-block)

Currently, if I search with keywords that only exist in a father-block, it only shows the father-block itself, and no child-preview when hovering.
I need more context in the search panel. I really need a way to see/check the child-blocks while searching.

You can preview the page which the father-block belongs to, but if the block is in the bottom part, it won’t be showed until scrolling down the page. I think that’s tedious and useless…
