"using ibm code snippets" » "using rbf code snippets", "using lbm code snippets", "using ibm code slippers"
"dung ve duoc snippets" » "dung va duoc snippets", "dung he duoc snippets", "dung de duoc snippets", "dung te duoc snippets", "dung ve nuoc snippets", "dung che duoc snippets", "dung ve duoc slippers"
"locating bug code 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 ibm code snippets\") OR (\"dung ve duoc snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using ibm code snippets ) OR ( dung ve duoc snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using ibm code snippets") OR ("dung ve duoc snippets"))) OR ("locating bug code snippets"))*.
