Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"cua van mo snippets" » "cua ban mo snippets", "cua dan mo snippets", "cua vat mo snippets", "cua van mao snippets", "cua van do snippets", "cua van ho 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: "((((\"cua van mo snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( cua van mo snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cua van mo snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
