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"
"cau vi tinh snippets" » "cau va tinh snippets", "cac vi tinh snippets", "cay vi tinh snippets", "cau vi tinh 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: "((((\"cau vi tinh snippets\") OR (\"python using data snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( cau vi tinh snippets ) OR ( python using data snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cau vi tinh snippets") OR ("python using data snippets"))) OR ("locating bug code snippets"))*.
