Perhaps you should try some spelling variations:
"vi chinh code snippets" » "vi chinh cong snippets", "vi chinh che snippets", "va chinh code snippets", "ve chinh code snippets", "tai chinh code snippets"
"using data java snippets" » "using java java snippets", "using sat java snippets", "missing data java snippets"
"locating bug core snippets" » "locating bug 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: "((((\"vi chinh code snippets\") OR (\"using data java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( vi chinh code snippets ) OR ( using data java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vi chinh code snippets") OR ("using data java snippets"))) OR ("locating bug core snippets"))*.
