Have just discovered that it is not anymore possible to search lyrics on Tekstowo since search results are now shown within a Google container which is not parseable. |
|
Going to move the last commit with tekstowo change to a separate PR and handle this issue there. |

This commit introduces a distance threshold mechanism for the Genius and Google backends. - Create a new `SearchBackend` base class with a method `check_match` that performs checking. - Start using undocumented `dist_thresh` configuration option for good, and mention it in the docs. This controls the maximum allowable distance for matching artist and title names. These changes aim to improve the accuracy of lyrics matching, especially when there are slight variations in artist or title names, see #4791.
