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