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