+<h1>Expert: attributes streaming definition for indexing facets</h1>
+
+Steaming of facets attributes is a low level indexing interface with Lucene indexing.
+There are two types of category related streams:
+<ul>
+  <li><b>Category tokenizer stream</b> handles tokenization for a single category, 
+  e.g. for creating drill-down tokens.</li>
+  <li><b>Category list tokenizer stream</b> handles tokenization for multiple categories, 
+  e.g. for creating a counting list token, representing all the categories of 
+  a certain document.</li>
+</ul>
