Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"toan cau do snippets" » "toan cau code snippets", "toan cao do snippets", "toan ban do snippets", "toan tap do 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: "((((\"toan cau do snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( toan cau do snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("toan cau do snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
