Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"khi voi lua snippets" » "chi voi lua snippets", "khi doi lua snippets", "khi hoi lua snippets", "khi toi lua snippets", "khi vi lua snippets", "khi voi luc snippets", "khi voi lua 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 (\"khi voi lua snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( khi voi lua snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("khi voi lua snippets"))) OR ("locating bug code snippets"))*.
