Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"hang ca su snippets" » "hang va su snippets", "nang cao su snippets", "hang tai su snippets", "hang cua su snippets", "hang cao su snippets", "hang ca sau snippets", "hang ca su 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: "((((\"hang ca su snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( hang ca su snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hang ca su snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
