Perhaps you should try some spelling variations:
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets", "python using data slippers"
"day hoc duc snippets" » "dai hoc duc snippets", "dan hoc duc snippets", "day hoc duoc snippets", "day hoc nuoc snippets", "day hoc thuc snippets", "day hoc duc slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets", "locating bug core 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: "((((\"day hoc duc snippets\") OR (\"python using data snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( day hoc duc snippets ) OR ( python using data snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("day hoc duc snippets") OR ("python using data snippets"))) OR ("locating bug code snippets"))*.
