Doing a query on Scopus
The EDITOR()-field searches for editors, i.e. (usually) human individuals who edit a volume.
You are looking, instead, for a book's publisher. The correct field would thus be labelled BOOKPUB().
With the following query, I find 8 results:
DOCTYPE ( &quot;bk&quot; )  AND  BOOKPUB ( &quot;Wiley&quot; )  AND  KEY ( &quot;real time systems&quot; ) 
(Note that I added the operator AND between each field as well as quotation marks within the parentheses.)
