Perhaps you should try some spelling variations:
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"do lua cau snippets" » "do luat cau snippets", "do cua cau snippets", "do quan cau snippets", "dao luan cau snippets"
"locating bug code snippets" » "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: "((((\"do lua cau snippets\") OR (\"python using data snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( do lua cau snippets ) OR ( python using data snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("do lua cau snippets") OR ("python using data snippets"))) OR ("locating bug code snippets"))*.
