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