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"
"o cac phan snippets" » "o cac nhan snippets", "o cao phan snippets", "o cap phan snippets", "o cac phan 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: "((((\"python using java snippets\") OR (\"o cac phan snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( o cac phan snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("o cac phan snippets"))) OR ("locating bugs code snippets"))*.
