Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"k toan can snippets" » "k toan ban snippets", "k toan cao snippets", "k toan cau snippets", "ke toan can snippets", "_ toan can snippets", "k tan can 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: "((((\"k toan can snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( k toan can snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("k toan can snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
