Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"cu dan hang snippets" » "cu ban hang snippets", "cu van hang snippets", "cu dat hang snippets", "cua dan hang snippets", "ca dan hang snippets", "co dan hang snippets", "cu dan hang 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: "((((\"python using java snippets\") OR (\"cu dan hang snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( cu dan hang snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("cu dan hang snippets"))) OR ("locating bug code snippets"))*.
