hierarchy - Solr: how to set up DIH for taxonomy faceting? -
i watched lucid webcast: http://www.lucidimagination.com/solutions/webcasts/faceting
it talks encoding hierarchical categories facilitate faceting. category "path" of "nonfic>science" encoded multivalues 0/nonfic & 1/nonfic/science.
1) categories stored in database coded numbers instead of spelled out names. example have category of 2/7 , lookup dictionary convert 2/7 nonfic/science. how do such lookup in dih?
2) once have spelled out category path such nonfic/science, how turn 0/nonfic & 1/nonfic/science using dih?
3) of categories multi-words containing whitespaces, such "computer science" , "functional programming", i'd have facet values such 2/nonfic/computer science/functional programming. how handle whitespaces in case? filtering fq still work?
thanks
