Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"dan tu lang snippets" » "dan cu lang snippets", "dan tu lanh snippets", "dan xu lang snippets", "danh tu lang snippets", "dan su lang snippets", "ban tu lang snippets", "dan tu lang 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: "((((\"dan tu lang snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dan tu lang snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dan tu lang snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
