Plex ignores articles (the, le, la, les...) in sort and search

If you want Plex to ignore all articles, set ArticleStrings to "".

Then Refresh Metadata on a few items.

Then check the Sort Title on those items.

Then Optimize the Database. Plex updates the search indexes during that process.

Test a few searches for those items.

If that works, Refresh Metadata on the entire Library.
