phrase boosting work here.

you'll need use edismax query parser along pf field.

the following params appended query should trick: &deftype=edismax&pf=company.

i've tested out on solr-5.4.1 dataset you've posted above , results follows:

query: http://localhost:8983/solr/test/select?q=company%3aaetnamho&wt=json&indent=true&deftype=edismax&pf=company&stopwords=true&lowercaseoperators=true&omitheader=true
