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