I don't think this is actually that much related to LTR Solr Feature.
In the Solr feature I see you specify a query with a specific query parser
(field).
Unless there is a bug in the SolrFeature for LTR, I expect the query parser
you defined to be used[1].
This means :
"rawquerystring":"{!field f=full_name}alessandro benedetti",
"querystring":"{!field f=full_name}alessandro benedetti",
"parsedquery":"PhraseQuery(full_name:\"alessandro benedetti\")",
"parsedquery_toString":"full_name:\"alessandro benedetti\"",
In relation to multi term EFI, you need to pass
efi.example='term1 term2' .
If not just one term will be passed as EFI.[2]
This is more likely to be your problem.
I don't think the dash should be relevant at all
