Extending search.separator seems not to work

[Kevin-De-Koninck]

Description

plugins[].search.separator seems not to work in version 1.5 (tested with 1.5.2 and 1.5.3). I extended it with ''[\s-.]+'' in order to allow searching for dots. But this change is not reflected in the search results. as soon as I add a dot in the search box, no results appear.

The relevant config snippet:

plugins:
  - search:
      separator: '[\s\-\.]+'  # Add dot as a word separator

The previous version that I used was 1.2.3. In that version, extending the search separator worked.
