Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"ha trong van snippets" » "ha trong cac snippets", "hoa trong van snippets", "hai trong van snippets", "hat trong van snippets", "ha trong van slippers"
"using a java snippets" » "using _ java snippets", "using a java 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: "((((\"ha trong van snippets\") OR (\"using a java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( ha trong van snippets ) OR ( using a java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("ha trong van snippets") OR ("using a java snippets"))) OR ("locating bugs code snippets"))*.
