Remote Access To Schema Data
Hi:
I want to get a list of the fields and field types for an index deployed on a Solr server (over HTTP or embedded). I can't see any obvious way to do this as a client.
This is part of the use case for an app we are working on where all field information for an index is available and we can programmatically format updates and queries based on the available fields.
Thanks,
Clay Fink

The LukeRequest class gets me what I wanted. Thanks!

Nice. I didn't know that. Thanks Erik.

It's fast if you say &numTerms=0 though, which is good enough to get
field/type info.

Hit /admin/luke to get luke's output as an XML which you can parse. You can
also hit /admin/file/?file=schema.xml. If you are using Solrj, you'd need to
set qt=/admin/luke or qt=/admin/file for this to work.
Note that the luke handler gives out a lot of information like term
frequency and therefore takes a longer time to execute.

Thanks, Jeff.
Luke will work , but it's a GUI - unless they expose an API that I can call. What I need is a way to get the informatiom as a client call to a SolrJ SolrServer object. We want to be able to get this info whether we are running Solr embedded or as a Web service. I guess I could write a request handler to return this info, but I like to see what's the "right" way to do this.

Fastest way I know of to get the schema is using the luke browser.
http://localhost/solr/admin/luke
It returns in xml and has tons of info you probably aren't interested it.
However, it does contain information like fields and type.
