Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"do quan va snippets" » "do quang va snippets", "dao quan va snippets", "co quan va snippets", "do quan vi snippets", "do quan ha snippets", "do luan va snippets", "do quan va 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 quan va snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( do quan va snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("do quan va snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
