"vi dung tren snippets" » "vi dung trong snippets", "vi dung trung snippets", "va dung tren snippets", "vi ung tren snippets", "vi dong tren snippets", "vi dung tren slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets", "locating bug core snippets"

• Removing quotes may allow a broader search: (((( vi dung tren snippets ) OR ( using data java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vi dung tren snippets") OR ("using data java snippets"))) OR ("locating bug code snippets"))*.
