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 tinh ly snippets" » "va tinh ly snippets", "vi trinh ly snippets", "vi sinh ly snippets", "vi dinh ly snippets", "vi tinh ly 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: "((((\"vi tinh ly snippets\") OR (\"using data java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( vi tinh ly snippets ) OR ( using data java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vi tinh ly snippets") OR ("using data java snippets"))) OR ("locating bugs code snippets"))*.
