Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"phi van ham snippets" » "phi san ham snippets", "thi van ham snippets", "phi va ham snippets", "phi van tham snippets", "phi van pham snippets", "phi van nam snippets", "phi van ham 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: "((((\"phi van ham snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( phi van ham snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("phi van ham snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
