In Datomic, querying field history with no retractions?

I'd like to get the history of values for a particular field in Datomic. My intuition is to use (d/history) like

(d/q '[:find ?entity ?field-val ?date ?tx
       :in $
       :where 
          [?entity :namespace/field ?field-val ?tx]
          [?tx :db/txInstant ?date]]
      (d/history (db/get-db)))

However, this query will duplicate most values because it lists every retraction as well as every value update (every db/add and db/retract).

I thought maybe I could query the datoms with the transaction, then check the operations. But I can't find a way to query the datoms.

(d/pull db '[*] tx-id) doesn't include datoms.
search engine results were not helpful for keywords like "query datomic transaction datoms"
searching for datomic transaction schema is not fruitful

I can use tx-range, but that seems unweildly.

Any better approaches?

Solution

I was looking in the wrong place. History queries offer an extra hidden positional value described in the history docs.

So any where clause can include ?entity ?attribute ?value ?transaction ?operation.

?operation is true for :db/add and false for :db/retract

So, the query I want looks like

(d/q '[:find ?entity ?field-val ?date ?tx
       :in $
       :where 
          [?entity :namespace/field ?field-val ?tx true] ;;ADDED TRUE
          [?tx :db/txInstant ?date]]
      (d/history (db/get-db)))
