you have stemming enabled for the field? stemming will make your wildcards
behave strangely. I would recommend you turn it off. because stemming likely
turned factory into factori or similar

wildcard queries are not analyzed, so they are not lowercased and in fact
case sensitive..., but if you lowercased all your terms in your analyzer
then Ira? will not match "Iraq" because "Iraq" was downcased to "iraq" at
index time.
