Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"he moi code snippets" » "he moi co snippets", "he moi cong snippets", "he moi con snippets", "ve moi code snippets", "te moi code snippets", "he noi code snippets"
"locating bug core snippets" » "locating bug code 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: "((((\"he moi code snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( he moi code snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("he moi code snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
