Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"thu trong o snippets" » "thuc trong o snippets", "thue trong o snippets", "thuy trong o snippets", "thu trong co snippets", "thu trong _ snippets", "thu trong 2 snippets"
"locating bug code snippets" » "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 trong o snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( thu trong o snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thu trong o snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
