Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"python using java snippets" » "python using data snippets", "python using java slippers"
"cua he dan snippets" » "cua che dan snippets", "cua te dan snippets", "cua le dan snippets", "cua ke dan snippets", "cua he dai snippets", "cua he dan slippers"

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: "((((\"cua he dan snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( cua he dan snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cua he dan snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
