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