Implementing Tagging and Excluding Filters with Solrj / Spring Data Solr

Question

I am trying to implement a Solr Facet search with multi-select on a field. To take this example: http://docs.lucidworks.com/display/solr/Faceting#Faceting-LocalParametersfor

Answer 1

With link I can do this :-

ModifiableSolrParams params = new ModifiableSolrParams();
params.add("fq", "{!tag=dt}doctype:pdf");
params.add("facet.field", "{!ex=dt}doctype");

Answer 2

The following block should create the querystring you want.

SimpleFacetQuery query = new SimpleFacetQuery(new SimpleStringCriteria("mainquery"))
  .addFilterQuery(new SimpleQuery(new Criteria("status").is("public")))
  .addFilterQuery(new SimpleQuery(new Criteria("{!tag=dt}doctype").is("pdf")));
query.setFacetOptions(new FacetOptions("{!ex=dt}doctype"));

solrTemplate.queryForFacetPage(query, YourBean.class);
