Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"tom dan thi snippets" » "tom van thi snippets", "tam dan thi snippets", "nhom dan thi snippets", "tom dang thi snippets", "tom tran thi snippets", "tom dinh thi snippets", "tom dan thi 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: "((((\"tom dan thi snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( tom dan thi snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("tom dan thi snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
