Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"using data java snippets" » "using java java snippets", "using sat java snippets", "missing data java snippets", "using data java slippers"
"vi lua hanh snippets" » "vi luat hanh snippets", "vi luu hanh snippets", "vi lu hanh snippets", "vi lua hanh slippers"

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 data java snippets\") OR (\"vi lua hanh snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using data java snippets ) OR ( vi lua hanh snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using data java snippets") OR ("vi lua hanh snippets"))) OR ("locating bugs code snippets"))*.
