Steps to replicate the issue (include links if applicable):
- Visit Special:NewPagesFeed
- Click "Set filters"
- Click the "Keyword search" radio button
- Make sure the keyword search box is empty
- Click "Set filters"
What happens?:
- "Has keyword: $1" chip
- 9,021 results
- API is doing some kind of filtering, perhaps for the number "1", e.g. LIKE '%1%'
What should have happened instead?:
- no "Has keyword" chip
- 13,623 results
- API should silently ignore this blank keyword filter because it is invalid
