In Ferret, allow documents with no title to match query terms by using LEFT JOIN on the "title" ranking field
This means that documents with no title (which don't have this field) are always excluded from the result set.
We'd prefer to include them, just not give them any bonus ranking/relevance boost. Use a LEFT JOIN so they get included.
- Applied D20650 (diff 1), made it use raw getTitle() as the document title, indexed a paste with no title.
- Searched for a term in the paste body.
- Before change: no results.
- After change: found result.
