Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"can ve tinh snippets" » "ban ve tinh snippets", "dan ve tinh snippets", "can va tinh snippets", "can ve tinh slippers", "can ve trinh snippets", "can ve dinh snippets", "can ve minh snippets"
"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: "((((\"python using java snippets\") OR (\"can ve tinh snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( can ve tinh snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("can ve tinh snippets"))) OR ("locating bug code snippets"))*.
