Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"lang van chi snippets" » "dang van chi snippets", "tang van chi snippets", "hoang van chi snippets", "lang van chien snippets", "lang luan chi snippets", "lang van chat 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 java code snippets\") OR (\"lang van chi snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( lang van chi snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("lang van chi snippets"))) OR ("locating bugs code snippets"))*.
