Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"danh het va snippets" » "danh viet va snippets", "danh hieu va snippets", "danh bat va snippets", "danh hat va snippets", "danh ket va snippets", "danh hut va snippets", "danh het 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: "((((\"danh het va snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( danh het va snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("danh het va snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
