Google sheets - Condition formatting using OR criteria based on multiple columns

Question

I'm looking to highlight a number of cells using conditional formatting based on the value of another cell which I've got working using

A2:A995
=search("Eaten",$B:$B) 

I'm trying to extend this to pick up all other columns as that match the same search criteria trying the below

A2:A996,C2:C995,E:E995 
=search("Eaten",$B:$B,$D:$D,$F:$F)
=OR(search("Eaten",$B:$B),search("Eaten",$D:$D)

It would be good if someone can point me in the right direction for this

Answer 1

custom formula: =ARRAYFORMULA(IF(B1:H="Eaten", 1))

Answer 2

In this instance you can just use

=b2="Eaten"

as the custom formula and the rest follows by relative addressing.
