Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"tin da lieu snippets" » "tin du lieu snippets", "tin da dieu snippets", "tin vat lieu snippets", "tinh da lieu snippets", "tin di lieu snippets", "tin va lieu snippets", "tin da lieu 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: "((((\"tin da lieu snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( tin da lieu snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("tin da lieu snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
