Search problem

When I search “John Description” (for example) and trying to find email where “John” is sender and “Description” is part of message, I get nothing. I must write “John text:Description” in search field (or use advanced search). If both words are in subject or both words are in message body - it works, but not when one word is part of sender and second - part of message body.

In Opera Mail similar search field (also indexed) works perfect without need to add “text:” or whatever.

Is possible to made that field in eM Client more flexible to search every word in every field?
