With the help of this list, I solved a similar issue by altering my query as follows:
Before (did not return full word matches): q=searchTerm* After (returned full-word matches and wildcard searches as you would expect): q=searchTerm OR searchTerm* You can also boost the exact match by doing the following: q=searchTerm^2 OR searchTerm* Not sure if the NGram changes things or not, but it might be a starting point.

When I insert "arkadicolson" into Solr and search for "arkadic", solr will find a match. When searching for "arkadicols", Solr will not find a match because the maxGramSize is set to 8. However when searching for the full word "arkadicolson" Solr will also not match. Is there a way to also match full word in combination with NGram?
