Classifying this as a bug because it's a regression from D7 where you could filter on tags.
Currently the views overview page only filters by name and description. This makes the tag column pretty pointless (and the whole option to tag a view in general).
Steps to reproduce:
- Go to admin/structure/views
- Search for 'default'
expected result: The views tagged with 'default' show up
actual result: no views show up
