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 cong van snippets" » "cua cong vang snippets", "cua cong san snippets", "cua song van snippets", "cua cong van 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: "((((\"using java java snippets\") OR (\"cua cong van snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( cua cong van snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java java snippets") OR ("cua cong van snippets"))) OR ("locating bugs code snippets"))*.
