title: Single schema versus multiple schemas in solr for different document types
body: <p>What is the general rule of thumb when deciding between creating multiple schemas versus creating a single consolidated schema for different document types.</p>
  
  <p>For example, if I want to index a collection of products and a collection of articles, what general rules should be followed to determine whether they should be created in one schema (and then use solr fq filter query to filter on the document type) or created in two schemas. The number of overlapping fields? The need to return data across both document types and also be able to filter to a single type? </p>
