> It is a common requirement that a single page requires to fire multiple queries .In cases
where these queries are independent of each other. If there is a handler which can take in
multiple queries , run them in paralll and send the response as one big chunk it would be
useful
> Let us say the handler is  MultiRequestHandler
> {code}
> <requestHandler name="/multi" class="solr.MultiRequestHandler"/>
> {code}
> h2.Query Syntax
> The request must specify the no:of queries as count=n
> Each request parameter must be prefixed with a number which denotes the query index.optionally
,it may can also specify the handler name.
> example
> {code}
> /multi?count=2&1.handler=/select&1.q=a:b&2.handler=/select&2.q=a:c
> {code}
> default handler can be '/select' so the equivalent can be
> {code} 
> /multi?count=2&1.q=a:b&2.q=a:c
> {code}
> h2.The response
> The response will be a List<NamedList> where each NamedList will be a response
to a query.
