It should be correct results when you search for the title
There has a lot of issues when we search for files.
Microsoft has some actions when search crawlers work.
However, it is a common habit when you search for files with title keywords.
It doesn't mean you need to depart some words or directories on the title.
All we want to have is using some words containing on the title to search for files.
It should be like the following scenario.
search a --> works!
search b --> works!
search fg123 --> works!
This is more user-friendly. I hope it could be modified in the future.
