Perhaps you should try some spelling variations:
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"locating bug core snippets" » "locating bug code snippets"
"mau tu code snippets" » "mau bug code snippets", "mau thu code snippets", "dau tu code snippets", "cau tu code 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 (\"mau tu code snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using data snippets ) OR ( mau tu code snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using data snippets") OR ("mau tu code snippets"))) OR ("locating bug core snippets"))*.
