interrogazione Solr per gli articoli con campo: valore o nessun valore per il campo per tutto

Question

Sto provando a interrogare Solr per le voci che hanno un determinato valore in un campo O nessun valore per il campo. Il valore del campo negato funziona quando usato da solo, ma fa sì che la query non restituisca risultati quando combinata con qualcos'altro. Di seguito è riportata una risposta con debugQuery abilitato. Il file di configurazione che uso può essere trovato here.

OR NOT query possono essere scritte come, usando il mio caso come un esempio:

im_cck_field_affected_plants:20 OR (*:* -im_cck_field_affected_plants:[* TO *])
