How to filter a specific buffer using grep or a word with lines in Snacks.picker?

[nitaicharan]

I tried using Snacks.picker.grep to filter only the focused (0) buffer, but it searches across all opened buffers instead. I also tried passing the search parameter to Snacks.picker.lines, but it doesn't filter the word I'm looking for.

Is there a way to filter by a word using lines or to specify a particular buffer in grep?
