stub out a tiny bit of Solr code, add jars
start to stub out a solr query
reuse HttpSolrServer per https://wiki.apache.org/solr/Solrj#HttpSolrServer
index more fields, start relying on solrpoc schema:

https://github.com/dvn/solrpoc
change getHitIds() param from Query to SolrQuery

Query: http://lucene.apache.org/core/old_versioned_docs/versions/3_0_0/api/core/org/apache/lucene/search/Query.html
SolrQuery: http://lucene.apache.org/solr/4_1_0/solr-solrj/org/apache/solr/client/solrj/SolrQuery.html
prevent silent failure when Solr is down
catch more SolrServerException per clean and build
