Hi, 
 
Below is the code I used to create such a rule. 
 
This rule uses one input "customField1" (Text) and a constant containing a group with all users. You can use this rule to pass in the customField1 value you are searching for to return an array of users. 
 
with( 
 local!userDictionary: a!forEach( 
 items: getdistinctusers( 
 cons!AllUsers 
 ), 
 expression: { 
 user: fv!item, 
 customField1: user( 
 fv!item, 
 "customField1" 
 ) 
 } 
 ), 
 index( 
 local!userDictionary, 
 "user", 
 wherecontains( 
 ri!customField1, 
 touniformstring( 
 local!userDictionary.customField1 
 ) 
 ), 
 null 
 ) 
) 
 
I hope this is useful.
