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"
"thuc va s7 snippets" » "thuc vat s7 snippets", "thuc dan s7 snippets", "thuc day s7 snippets", "thuc va su snippets", "thuc va so 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: "((((\"thuc va s7 snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( thuc va s7 snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thuc va s7 snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
