(when benchmark 1. don't forget to enable http connection pooling on the client side) Regarding the 2. - passing the long disjunction is a well known road block (it's not a really natural problem for search engines). Most of approaches is described at http://lucene.472066.n3.nabble.com/Solr-large-boolean-filter-td4070747.htmlthere is even some code at github! If you see that stored fields is a slowpoke, but only if you do, you can consider https://wiki.apache.org/solr/FieldCollapsing , however it's also known as a bottleneck.
