Perhaps you should try some spelling variations:
"lochating bug code snippets" » "locating bug code snippets", "lochating bug core snippets"
"python using java snippets" » "python using data snippets"
"cu mat cua snippets" » "cu ma cua snippets", "cu manh cua snippets", "cu mang cua snippets", "cu cat cua snippets", "co mat cua 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: "((((\"cu mat cua snippets\") OR (\"python using java snippets\"))) OR (\"lochating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( cu mat cua snippets ) OR ( python using java snippets ))) OR ( lochating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cu mat cua snippets") OR ("python using java snippets"))) OR ("lochating bug code snippets"))*.
