Perhaps you should try some spelling variations:
"creating cao dan snippets" » "creating a dan snippets", "creating _ dan snippets", "creating _ao dan snippets", "creating aao dan snippets", "creating cao dang snippets", "creating cao danh snippets", "creating cac dan snippets", "creating cao dan slippers"
"creating c a snippets" » "creating _ a snippets", "creating a a snippets", "creating c va snippets", "creating c a slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets", "locating bug core snippets"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"creating cao dan snippets\") OR (\"creating c a snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( creating cao dan snippets ) OR ( creating c a snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("creating cao dan snippets") OR ("creating c a snippets"))) OR ("locating bug code snippets"))*.
