Re: Newbie Solr questions
thanks, so there is no way to create custom documents/field via the SolrJ client API @ runtime.? On Nov 16, 2009, at 4:49 PM, Lance Norskog wrote: here is no way to create custom documents/fields via the SolrJ client @ runtime.
Re: Newbie Solr questions
ok, so what I am hearing, there is no way to create custom documents/ fields via the SolrJ client @ runtime. Instead you have to use the schema.xml ahead of time OR create a custom index via the lucene APIs then import the indexes into Solr for searching?
