Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"do hai duc snippets" » "do hoai duc snippets", "do mai duc snippets", "do hai cuc snippets", "do thai duc snippets", "doc hai duc snippets", "do dai duc snippets", "do hai 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: "((((\"do hai duc snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( do hai duc snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("do hai duc snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
