Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"dan su hoa snippets" » "dan su code snippets", "dang su hoa snippets", "dan su hoan snippets", "dan su hoat snippets", "dan su khoa 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: "((((\"dan su hoa snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( dan su hoa snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dan su hoa snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
