Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"tu minh dat snippets" » "tu dinh dat snippets", "tu minh dao snippets", "tu minh danh snippets", "thu minh dat snippets", "vu minh dat snippets", "thi minh dat snippets", "tu minh dat 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: "((((\"tu minh dat snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( tu minh dat snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("tu minh dat snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
