Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using data java snippets" » "using java java snippets", "using sat java snippets", "missing data java snippets"
"do luong cho snippets" » "do luong chu snippets", "do luong khoa snippets", "do luong theo snippets"

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 data java snippets\") OR (\"do luong cho snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using data java snippets ) OR ( do luong cho snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using data java snippets") OR ("do luong cho snippets"))) OR ("locating bugs code snippets"))*.
