Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"tri van dat snippets" » "thi van dat snippets", "tri va dat snippets", "trinh van dat snippets", "tri van dao snippets", "tri van dau snippets", "tri dan dat snippets", "tri van 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: "((((\"python using java snippets\") OR (\"tri van dat snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( tri van dat snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("tri van dat snippets"))) OR ("locating bug code snippets"))*.
