Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"toc do lieu snippets" » "toc du lieu snippets", "toc so lieu snippets", "toc da lieu snippets", "toc dao lieu snippets", "toc co lieu snippets", "hoc do lieu snippets", "toc do lieu 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: "((((\"toc do lieu snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( toc do lieu snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("toc do lieu snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
