Hi again,Isn't 'preImportDeleteQuery' a Solr 1.4 feature? I'm unable to
import only the entities I want, all the index is deleted.
In all entities I have a field that is unique by entity ('alias') and I
configured the preImportQuery in all entities like this: alias: '<entity
name>'.
Thanks in advanced,
Rui Pereira
