in an Solr 4.8 schema I have a fieldType with few SynonymFilter filters at
index and few at query time.
Moving this old schema to Solr 7.3.0 I see that if I use SynonymGraphFilter
during indexing, I have to follow it with FlattenGraphFilter.
I also know that I cannot have multiple SynonymGraphFilter, because produce
a graph but cannot consume an incoming graph.
So, should I add an FlattenGraphFilter after each SynonymGraphFilter at
index time to have more than one?
And, again, how can I have many SynonymGraphFilter at query time? :)
Thanks in advance for your time.
