Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"dang using java snippets" » "dang sinh java snippets", "data using java snippets", "dang ung java snippets", "dang using data snippets"
"using c core snippets" » "using lc core snippets", "using a core snippets", "using _ core 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 c core snippets\") OR (\"dang using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using c core snippets ) OR ( dang using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using c core snippets") OR ("dang using java snippets"))) OR ("locating bugs code snippets"))*.
