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"
"hoa lang xa snippets" » "hoa dan xa snippets", "hoa van xa snippets", "hoa lang ha snippets", "hoa dang xay snippets", "hoa lang van 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: "((((\"hoa lang xa snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( hoa lang xa snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hoa lang xa snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
