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
