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"
"toc pu cao snippets" » "toc phu cao snippets", "toc pa cao snippets", "toc cu cao snippets", "toc vu cao snippets", "toc su cao 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: "((((\"toc pu cao snippets\") OR (\"python using java snippets\"))) OR (\"lochating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( toc pu cao snippets ) OR ( python using java snippets ))) OR ( lochating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("toc pu cao snippets") OR ("python using java snippets"))) OR ("lochating bug code snippets"))*.
