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