V10 Two-word searches can fail if matches are in separate fields

Using:

Search bar damaged finds this message:

image

and RunningBull finds the same one:

image

matching in a different field, but damaged RunningBull does not find that message.

Anyone else getting this? Anyone know a workaround?

The documentation for Search Bar https://www.emclient.com/webdocumentation/en/10.0/eMClient/Default.htm#Getting%20Started/Search.htm fails to actually say what the search does, but I assume such multi-word searches are supposed to work.
