Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"ban co duoc snippets" » "ban tao duoc snippets", "ban hoa duoc snippets", "ban hoc duoc snippets", "ban do duoc snippets", "san co duoc 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: "((((\"python using java snippets\") OR (\"ban co duoc snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( ban co duoc snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("ban co duoc snippets"))) OR ("locating bug core snippets"))*.
