Hi Johannes,
because it seems that LIKE operator and wildcards are not allowed in the
current implementation of Expressions symbology, my best suggestion
consists into using the Substring operator, e. g.

Substring([FIELD_NAME],0,6) == "string" || Substring([FIELD_NAME],1,7)
== "string"  || Substring([FIELD_NAME],2,8) == "string" ...and so on

depending on the of field length, so you have to change the
indexes properly in order to catch the substring. Hope this helps!
