Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"pha do ung snippets" » "phac do ung snippets", "pham do ung snippets", "phan do ung snippets", "pha do luong snippets", "pha do trung snippets", "pha do quang snippets", "pha do ung 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: "((((\"pha do ung snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( pha do ung snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("pha do ung snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
