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