Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"dan cho hoa snippets" » "dan cho code snippets", "danh cho hoa snippets", "san cho hoa snippets", "dac cho hoa snippets", "dan cho hoc snippets", "dan chi hoa snippets", "dan cho ho snippets"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing 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: "((((\"dan cho hoa snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( dan cho hoa snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dan cho hoa snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
