[jira] Commented: (SOLR-217) schema option to ignore unused fields

["Yonik Seeley (JIRA)" <ji...@apache.org>]

Yonik Seeley commented on SOLR-217:
-----------------------------------

This is a unique enough of a requirement, I'm not sure an additional configuration switch is warranted.

However, another solution might be to allow fields to be unstored *and* unindexed (essentially doing nothing).  That would allow you to map a dynamic field of "*" to an unstored + unindexed field.
It would also allow people to transition schemas + older clients.  They could change the old field to unstored + unindexed and use a copyField to move it to the new field.

> One thing that causes problems for me (and i assume others) is that Solr is schema-strict in that unknown fields cause solr to throw exceptions and there is no way to relax this constraint.  this can cause all sorts of serious problems if you have automated feeding applications that do things like SELECT * FROM table1 or where you want to add other fields to the document for processing purposes before sending them to solr but don't want to deal with 'cleanup'
