Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"cha me doan snippets" » "cha le doan snippets", "cha ket doan snippets", "cha de doanh snippets", "chat me doan snippets", "chua me doan snippets", "chan me doan 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: "((((\"cha me doan snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( cha me doan snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cha me doan snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
