"doi tuong va slippers" » "moi truong va slippers", "doi song va slippers", "doi truong va slippers", "doi thuong va slippers", "doi luong va slippers", "doi tuong va slippery", "doi tuong va grippers"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core snippets"

• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( doi tuong va slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java java snippets") OR ("doi tuong va slippers"))) OR ("locating bug code snippets"))*.
