If you want to find the commits that touched a specific text in a file, use
git log -S 'text in the code' -- path/to/file
If you use tig you may run a similar command to get a navigatable list of affected files:
tig -S'text in the code'
Example
Here is an example, where the move of the convert_number_column_value(value) method in active record is traced (simplified output):
git log -n 1 --pretty=oneline -S 'convert_number_column_value(value)' -- activerecord/lib/active_record/base.rb

- elsif value == true
