Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"than do dan snippets" » "than doc dan snippets", "thanh do dan snippets", "than vo dan snippets", "than do danh snippets", "than dao dan snippets", "than do dang snippets", "than do dan slippers"
"locating bug code snippets" » "locating bug code slippers", "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: "((((\"than do dan snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( than do dan snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("than do dan snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
