Enhance issue search, allow search using keyword
Description
- using keywords to searching issue title doesn't work, in example if you search "pages access control", you will get nothing in results, though there is issue with title "Make GitLab pages support access control"
- Search doesn't give you option to search exclusively in titles or descriptions, it will be nice if we get those options
(Include problem, use cases, benefits, and/or goals)
Proposal
- Add a filter option to search only within issue titles
- Add a filter option to search only within issue description
- Match keywords that are not in continuous string like "Page Control" in title should match with issue tilted "Make GitLab pages support access control"
