I should remove the parens before they confuse anyone. They are added by
the log statement. Without the parens:
{:company_profile_id ["2"], :topic :company, :url ["mikeshawauto.com"]}
field-name:
:company_profile_id
field-value:
["2"]
but I in the final document I only get:
"final document: " {:company_profile_id ["2"], :topic :company, :url ["
mikeshawauto.com"]}
I want:
"final document: " {:company_profile_id ["2" "2"], :topic :company, :url ["
mikeshawauto.com"]}
