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"
"hoc cao data snippets" » "hoc cao dang snippets", "hoc a data snippets", "hoc cao dam snippets", "hoc cao data 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: "((((\"hoc cao data snippets\") OR (\"using java java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( hoc cao data snippets ) OR ( using java java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hoc cao data snippets") OR ("using java java snippets"))) OR ("locating bugs code snippets"))*.
