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"
"n trinh thi snippets" » "n trinh tai snippets", "n trinh thiet snippets", "n trinh tu snippets", "p trinh thi snippets", "anh trinh thi snippets", "dan trinh thi snippets", "n trinh thi 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: "((((\"n trinh thi snippets\") OR (\"python using data snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( n trinh thi snippets ) OR ( python using data snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("n trinh thi snippets") OR ("python using data snippets"))) OR ("locating bug code snippets"))*.
