Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"chao den do snippets" » "cham den do snippets", "chao sen do snippets", "chao yen do snippets", "chao den o 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: "((((\"chao den do snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( chao den do snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("chao den do snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
