I want to know, how solr stores numerical (e.g., double) values inside the index. As they are, or solr converts them to some string representation (even if I use a multivalued field).
For type "double" in the example schema, they are stored exactly as given (text values), so don't try range queries. For "sdouble", see the NumberUtils class. The bits of the double are grabbed as a long, then manipulated so it will sort correctly as a signed long, and then chopped into chars that will UTF8 encode correctly (avoid range involving UTF16 surrogates).
Also for multiValued fields, is it possible to add more values to these kind of fields later during the crawl (adding several additional values to the values of an existing multi valued field).
Not currently. Lucene doesn't have this functionality, and thus Solr doesn't either. You have to add the complete document again. -Yonik
