Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"dong den do snippets" » "dong den code snippets", "dong dien do snippets", "don den do snippets", "dong dan do snippets", "dong den o 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: "((((\"dong den do snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( dong den do snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dong den do snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
