Perhaps you should try some spelling variations:
"using java java snippets" » "using data java snippets"
"bi trong cham snippets" » "bi trang cham snippets", "bi trong cac snippets", "bi trong nha snippets", "ro trong cham snippets", "le trong cham snippets", "ly trong cham snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug 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 java java snippets\") OR (\"bi trong cham snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( bi trong cham snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java java snippets") OR ("bi trong cham snippets"))) OR ("locating bug code snippets"))*.
