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