The old setup used to have context lines with the max parameter in the search query, however it's now deprecated it seems like.
src now only returns only the matching lines with no context above/beneath it.
The only way right now is to use --stream option for it to read the search.contextLines option, however its output mass highlights the entire search results, so the original query blends illegible.

Also is there any plans to view referenced files/TUI-like features?
