[jira] [Issue Comment Deleted] (SOLR-2412) Multipath hierarchical
faceting

Comment: was deleted
(was: Any suggestions on parsing the output?
The hierarchical faceting seems to be working as described, but in my test 3-level hierarchy, converting the query xml to a php array, it comes out being 13-levels deep. Parsing is complicated by the text strings of facet field being keys in the array. I have built a basic recursive function to parse the output, but after three days of trying, I am thinking there must be a better way to my desired result, which would be like a common html <ul> tree display. For a failed example of what I am trying:
Any suggestions appreciated.

> Hierarchical faceting with slow startup, low memory overhead and fast response. Distinguishing features as compared to SOLR-64 and SOLR-792 are
> * Multiple paths per document
> * Query-time analysis of the facet-field; no special requirements for indexing besides retaining separator characters in the terms used for faceting
> * Optional custom sorting of tag values
> * Recursive counting of references to tags at all levels of the output
> This is a shell around LUCENE-2369, making it work with the Solr API. The underlying principle is to reference terms by their ordinals and create an index wide documents to tags map, augmented with a compressed representation of hierarchical levels.
