Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"tri noi dan slippers" » "tri doi dan slippers", "tri moi dan slippers", "tri ngoai dan slippers", "tri hoi dan slippers", "tri noi da slippers", "tri noi dan slippery", "tri noi dan grippers"
"locating bug code snippets" » "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: "((((\"python using java snippets\") OR (\"tri noi dan slippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( tri noi dan slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("tri noi dan slippers"))) OR ("locating bug code snippets"))*.
