Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"phan su tri snippets" » "phan suc tri snippets", "phan tu tri snippets", "nhan su tri snippets", "phan su troi snippets", "phan su thi snippets", "phan su tai snippets", "phan su tri 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 (\"phan su tri snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( phan su tri snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("phan su tri snippets"))) OR ("locating bug code snippets"))*.
