"number of documents found" can be found in a field called "numFound" in 
the response.

If you do use SolrJ you will likely have a QueryResponse qr and can just 
do a qr.setNumFound().

If you use do not use SolrJ try to add e.g. wt=json to your search query 
to get the response in JSON. Find the numFound field in the readable 
JSON response - it should be at "response.numFound". If in javascript 
with jQuery something like this should work:
                 $.getJSON(search_url,
                   function(data) {
                     ... data.response.numFound ...
                   }
                 )
Go figure who to extract it in javascript without jQuery

I'd add rows=0, just to avoid the actual records serialization if size is
all that matters.

Query for "*:*" and look at the number of documents found.
