Re: sort on fields that are not mandatory in each document
Actually it is both field level and field type level. You decide based on your use case ( can happen that for the same field type , you want sortMissingFirst for one field, and sortMissingLast for another) . I want to add a bonus note, related the ( empty ) and null concept. Be very careful you don't index empty values for your fields or this will mess up the sorting. Solr manage the missing values ( that are null values), and does not manage the empty values. Those values for a human are identical to null values, but not for solr. So you can have very weird situations for your users. So , to be sure everything work nice with sortMissing attribute, be sure to not index empty values.
