Perhaps you should try some spelling variations:
"doi co hoat snippets" » "doi co code snippets", "doi cao hoat snippets", "doi che hoat snippets", "doi toi hoat snippets", "doi bo hoat snippets", "moi co hoat snippets", "hoi co hoat 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: "((((\"python using data snippets\") OR (\"doi co hoat snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using data snippets ) OR ( doi co hoat snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using data snippets") OR ("doi co hoat snippets"))) OR ("locating bug core snippets"))*.
