Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"bat cua hoc snippets" » "bat cua code snippets", "ban cua hoc snippets", "mat cua hoc snippets", "bai cua hoc snippets", "bat cua hoi snippets", "bat cua thuoc snippets", "bat cua nuoc 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: "((((\"bat cua hoc snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( bat cua hoc snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("bat cua hoc snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
