Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"can co vu snippets" » "can bo vu snippets", "ban co vu snippets", "san co vu snippets", "can co tu snippets", "can co va snippets", "can lo vu snippets", "can co vu 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: "((((\"can co vu snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( can co vu snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("can co vu snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
