Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"quan ho duc snippets" » "quan he duc snippets", "quan ha duc snippets", "quan so duc snippets", "quan hoc duc snippets", "quan do duc snippets", "quan hong duc snippets", "quan ho 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: "((((\"quan ho duc snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( quan ho duc snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("quan ho duc snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
