Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"tan cua dat snippets" » "than cua dat snippets", "tang cua dat snippets", "toan cua dat snippets", "tan cua dan snippets", "tan cua vat snippets", "tan cua dai snippets", "tan cua 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: "((((\"tan cua dat snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( tan cua dat snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("tan cua dat snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
