"Exact" search for certain fields
Add the functionality to do an "exact" search on certain fields. For example there are very short titles which can be search much better this way. Also signatures in the LCCallNumber field could be found much easier. We are api users (Backend Summon, Frontend VuFind) and are helping ourselves at the moment with "constructed" values for the (for example) LCCallNumber to simualte the possibility of an exact search - but this is far from optimal.
