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