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