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"
"hoi dang php snippets" » "hoi dan php snippets", "hoi lang php snippets", "hoi dong php snippets", "hoi bang php snippets", "hoi dang phi snippets", "hoi dang phat snippets", "hoi dang php 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 (\"hoi dang php snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( hoi dang php snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("hoi dang php snippets"))) OR ("locating bugs code snippets"))*.
