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