1. You don't actually put PDF/Word into Solr. Instead, it is run through content and metadata extraction process and then index that. This is important because "a computer" does not understand what you are looking for when you open a PDF. It only understand whatever text is possible to extract. In case of PDF it is often not much at all, unless it was generated with accessibility layer in place. You can experiment with what you can extract by downloading a standalone Apache Tika install, which has a command line version or using Solr's extractOnly flag. Solr, internally, uses Tika, so the results should be the same.
2) When you do a search you can do "field:(Keyword1 Keyword2 Keyword3 Keyword4) and you get as results any document that matches one of those. Not sure about 1000 of them in one go, but certainly a large number. On the other hand, if you have same keywords all the time and you are trying to match documents against them, you might be more interested in Elastic Search's percolator (http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-percolate.html ) or in Luwak (https://github.com/flaxsearch/luwak).
