You want to use \b
as word boundaries, as @gromi08 said:
\bbauvol\b
If you want to copy any portion of this word (so you can replace it, modify it, change the case, etc.) it is usually best to wrap it in (
and )
braces so you can reference them in the Replace box:
Find:
(\bbauvol\b)
Replace:
<some_tag>\1</some_tag>
Did you have anything specific you were trying to do with the result once you found it (cut it, duplicate it, etc.)?
