Update search-syntax.md (MicrosoftDocs#3364)

Tidied up this page based on the UPdated Web Site, including:
Ensured all the search items 'work'!
Removed unclear searches - it was not clear where there were two lines just what that meant. 
Remove quotes from search terms where they are not needed, but showed the use as an alternative.
