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