Perhaps you should try some spelling variations:
"creating duc anh snippets" » "creating a anh snippets", "creating duc anh slippers"
"creating _ a snippets" » "creating _ 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 _ a snippets\") OR (\"creating duc anh snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( creating _ a snippets ) OR ( creating duc anh snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("creating _ a snippets") OR ("creating duc anh snippets"))) OR ("locating bug code snippets"))*.
