I believe that having a front-end to Solr is a very typical use case. As yo=
u
refer to middleware above, introducing another layer between the front-end,
and Solr search on the back-end, might or might not make sense, depending
on your requirements. If you are using a web development framework, there
are already implementations of many such middleware layers that provide an
interface to Solr in a manner more "natural" to users of the framework. Tho=

Solr search is usually blazingly fast, the overhead of such middleware shou=
ld be
reasonable compared to the advantages it provides.

Well, presumably, one's search requirements stem from a website/application
that also provides other functionalities. In such a case, a layer over
Solr seems
almost unavoidable.
