Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"using java java snippets" » "using data java snippets", "using java java slippers"
"cua tap trac snippets" » "cua tap toan snippets", "cua tam trac snippets", "cua phap trac snippets", "cua tap trac 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 tap trac snippets\") OR (\"using java java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( cua tap trac snippets ) OR ( using java java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cua tap trac snippets") OR ("using java java snippets"))) OR ("locating bugs code snippets"))*.
