Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets", "using java core snippets", "using java code slippers"
"trong can wu snippets" » "trong canh wu snippets", "trong chan wu snippets", "trong cac wu snippets", "trong can we snippets", "trong fan wu snippets", "trong lan wu snippets", "trong can wu slippers"
"locating bug code snippets" » "locating bug core snippets", "locating bug code slippers", "locating bung code snippets", "locating bugs code 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 (\"trong can wu snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( trong can wu snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("trong can wu snippets"))) OR ("locating bug code snippets"))*.
