Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"khoi cua ta snippets" » "hoi cua ta snippets", "khi cua ta snippets", "kho cua ta snippets", "khoi cua tam snippets", "khoi cua tap snippets", "khoi cua tai snippets", "khoi cua ta 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: "((((\"khoi cua ta snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( khoi cua ta snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("khoi cua ta snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
