Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"python using java snippets" » "python using data snippets", "python using java slippers"
"lua doi su snippets" » "sua doi su snippets", "quan doi su snippets", "lua oi su snippets", "lua don su snippets", "lua voi su snippets", "lua doi su slippers"

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 (\"lua doi su snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( lua doi su snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("lua doi su snippets"))) OR ("locating bugs code snippets"))*.
