Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"lua van hac snippets" » "luan van hac snippets", "luu van hac snippets", "qua van hac snippets", "lua van hoc snippets", "lua van ha snippets", "lua van hai snippets", "lua van hac 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 (\"lua van hac snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( lua van hac snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("lua van hac snippets"))) OR ("locating bug code snippets"))*.
