Erk, haven't used /luke in years. Apologies. About that JS: does distributed search "do the right thing" when the distributed part is not implemented? Or does every script have to explicitly include distributed search support?

I've | used that trick to get a list of all *_facet dynamic fields to then | have my UI (Blackight's first prototypes, aka Solr Flare) turn | around and facet on them. The request to /admin/luke was done once | and cached. | | But I think what Torben is going for is the | "FieldsUsedUpdateProcessor" trick like | <https://issues.apache.org/jira/browse/SOLR-1280>. | | In Solr 4 there is a JavaScript update processor example, commented | out, that will add a field to every document containing the names of | the fields (constrained to the name pattern of attr_* in the | example) for that document. One can then use that to facet upon. | | In Solr 4, it's here: | <https://svn.apache.org/repos/asf/lucene/dev/tags/lucene_solr_4_0_0/solr/example/solr/collection1/conf/update-script.js> | | Note, the field name in a comment in there is incorrect (I'll commit | a fix), but if you used that update processor, you could then do a | query and facet on field attribute_ss and across that result set see | what fields are contained within it. I've seen this trick employed | at the Smithsonian first hand, where there are so many different | attributes across the documents that it's hard to know what the best | facets are for the result set. | | Erik | | | On Oct 27, 2012, at 04:09 , Lance Norskog wrote: | | > Nope!
