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