Perhaps you should try some spelling variations:
"dang hanh code snippets" » "dang thanh code snippets", "ban hanh code snippets", "dang van code snippets", "dang hanh de snippets", "dang hanh cong snippets", "dang hanh cad snippets", "dang hanh code slippers"
"using 3d code snippets" » "using 3 code snippets", "using a code snippets", "using _ code snippets", "using cfd code snippets", "using 3d code slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code 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: "((((\"using 3d code snippets\") OR (\"dang hanh code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using 3d code snippets ) OR ( dang hanh code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using 3d code snippets") OR ("dang hanh code snippets"))) OR ("locating bug code snippets"))*.
