First time on forum.
We are planning to use Solr to house some data mining formation, and we are
thinking of using attributes to add some semantic information to indexed
content. As a test, I wrote a filter that adds an "animal" attribute to tokens
like "dog", "cat", etc. After adding a document with my field (animal_text),
the attribute shows up in the analysis tab for the collection, so it seems to
have been processed. What I'm not sure of is how attributes are surfaced in the
index for search, either via an URL or programmatically. Any advice is
appreciated.
