Searching in text insets

[Whites]

Today, from within the main document, I searched on a string in a  
text inset and was surprised to find that the FM search function did  
not find it.
Am I being obtuse (happens a lot) or is this the way things are  
supposed to be?
Any help will be appreciated.
