FTS ConjunctionQuery Append not working

If we create an object of type ConjuctionQuery like:
ConjunctionQuerycq = new ConjunctionQuery(new MatchQuery(address.City).Field(“address.city”));
and then try to append to it by logic like:
if (!string.IsNullOrEmpty(address.CountryCode))
cq.Prepend(new MatchQuery(address.CountryCode).Field(“address.countryCode”));

The append do nothing! asp.net core 5, couchbase client version 3.2.0

@Shlomo_Shs -

ConjunctionQuery does not have a Prepend/Append method. It does have a And method. Maybe that is what you are looking for?
