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