Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"doi ton duc snippets" » "doi tan duc snippets", "doi toi duc snippets", "doi tuong duc snippets", "doi tran duc snippets", "doi tong cuc snippets", "doi tinh duc snippets", "doi ton duc 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: "((((\"doi ton duc snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( doi ton duc snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("doi ton duc snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
