Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"using java code snippets" » "using data code snippets", "using java code slippers"
"doi ca trong snippets" » "doi cay trong snippets", "doi cad trong snippets", "doi co trong snippets", "doi cua trong snippets", "duoi ca trong snippets", "doi ca trong 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: "((((\"using java code snippets\") OR (\"doi ca trong snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( doi ca trong snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("doi ca trong snippets"))) OR ("locating bugs code snippets"))*.
