Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"van ban nha slippers" » "van ban nhan slippers", "van ban phap slippers", "van ban than slippers", "van ban nha slippery", "van ban nha grippers"
"locating bug code snippets" » "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 (\"van ban nha slippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( van ban nha slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("van ban nha slippers"))) OR ("locating bug code snippets"))*.
