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"
"dat vu cua snippets" » "dat va cua snippets", "dat su cua snippets", "dao vu cua snippets", "dat hu cua snippets", "dat tu 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: "((((\"dat vu cua snippets\") OR (\"python using java snippets\"))) OR (\"lochating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dat vu cua snippets ) OR ( python using java snippets ))) OR ( lochating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dat vu cua snippets") OR ("python using java snippets"))) OR ("lochating bug code snippets"))*.
