Subject: [jira] [Commented] (SOLR-3251) dynamically add field to schema

Robert Muir commented on SOLR-3251:
-----------------------------------

On a normal search-side request, yes. Some things may need the latest schema though... like a codec provider, perhaps realtime-get, the future code to add new fields on demand (aka type guessing), etc. 
{quote}

But my problem is with the API: an IndexSearcher is absolutely the worst place to have a getter for a moving target: because its all about search.

If for example, realtime-get wants to get the 'latest', it should get it from request.getCore().getCurrentSchema() (please, name it in such a way that its not confusing).

Otherwise in general things should use request.getSchema(). SolrIndexSearcher should not expose the schema: there need not be 3 different ways, 2 of which have "current" semantics and one of which is immutable across the request. And its own internal use of "moving target" should be carefully contained.
