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