Search in Notes of Business Partner or Business Transaction

Hi experts,

The standard search offers only normal fields for selection (ID, Name, Date etc.), but how about searching in notes.

Is it possible to search for Business Partners or Business Transactions based on the notes?

E.g. Show me all accounts which have the text "Important customer" inside their notes.

Is it maybe possible with the TREX Search?

Thanks for your help,

Wladimir
