Jan Høydahl commented on SOLR-2368:
-----------------------------------

When I try to think practically on this, satisfying the vast majority of 
customers, locking down stuff has been a customer requirement in perhaps 2-3 of 
the almost 100 enterprise installations I've done over the last 11 years. The 
FAST search engine and its FQL query language by defaults exposes all features 
and (internal) fields to the end user, and there is no way to lock it down 
except through custom coding. If it's good enough for the largest enterprise 
customers out there, I'm sure it's good enough for Solr users. If someone need 
more locking down, let them contribute that - they won't sue anyone, this is 
collaboration :-)

This public news site runs Solr 1.4.2-dev with SOLR-1553:

Can anyone show a practical examples of queries end users can do here to 
crash/break the system or security in any way? I can construct one: 
http://www.rechargenews.com/search?q=norway:s+oil in which the first clause 
triggers the known foo:bar bug but I cannot see any realistic worryable 
examples.

Making edismax the default now (with an explicit way to switch to the old) and 
finalizing baking in 3.2 before summer would be a win win, at least for those 
of my customers who are planning to release on 3.1 in the coming months, all of 
them using edismax already.
