Unused argument defined: search.py: function multi_bw in line 192 (family defined but not used inside function)

[xyluo25]

Hi Developers,

Please check the following code:

The argurment family defined as one paramter for function multi_bw but not used inside the function.

Possible solution:

1. Remove this unused argument (this will change the codebase as the function used inside many functions)
2. Keep this argument and add comment inside the docstring to explain this is not used in the function.
   Any other suggestions on this issue?
