Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"duoc ha dan snippets" » "duoc ma dan snippets", "duc ha dan snippets", "duoc va dan snippets", "duoc hoa dan snippets", "duoc hat dan snippets", "duoc ha dang 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: "((((\"duoc ha dan snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( duoc ha dan snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("duoc ha dan snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
