Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"trong lua can snippets" » "trong lua code snippets", "trong qua can snippets", "trong luu can snippets", "trong cua can snippets", "trong luat can snippets", "trong lua cau snippets"
"dung java java snippets" » "dung va java 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: "((((\"dung java java snippets\") OR (\"trong lua can snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( dung java java snippets ) OR ( trong lua can snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung java java snippets") OR ("trong lua can snippets"))) OR ("locating bug core snippets"))*.
