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