1) General way is:

    s1 = myVarChar.FindContains("Ruslan")

    s2 = myVarChar.FindContains("Erik")

    s1.Intersection( s2 )

        // hmm, may be we need also add
        // s3 = Intersection( s1, s2 )


2) second way

    s1 = myVarChar.FindContains("Ruslan")

    s2 = myVarChar.FindContains("Erik", s1)
    
        s1 = nil // to free RAM ASAP
