It seems like $field defined by parameter $field on line 138 can also be of type string; however, BestServedCold\LaravelZendSearch\Lucene\Search::singleTerm() does only seem to accept boolean, maybe add an additional type check?

It seems like $this->index->limit($this->limit)->open($this->path)->get()->find($this->query->getBoolean()) targeting ZendSearch\Lucene\Index::find() can also be of type object<ZendSearch\Lucene\Search\QueryHit>; however, BestServedCold\LaravelZendSearch\Lucene\Search::mapIds() does only seem to accept array, maybe add an additional type check?
