Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"quan cua da snippets" » "quan cua code snippets", "quan luan da snippets", "ban cua da snippets", "gian cua da snippets", "quan cua dan snippets", "quan cua dai snippets", "quan cua dam 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: "((((\"quan cua da snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( quan cua da snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("quan cua da snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
