is the jsr implemented yet?
AFAIK it's not complete, but since Jackrabbit is also using Lucene and
considering posts like for example
http://jackrabbit.510166.n4.nabble.com/Need-a-complete-JCR-JQOM-example-query-td3944788.html
I would assume there is some active development.

I think I could first define this language by bnf and then use javacc
or antlr to implement.
I have recently written a query rewriter component for our products
which defines regular expression like language that can rewrite querys.
. and also we can learn something from http://jsqlparser.sourceforge.net/
I have experimented it to check sql injections.

I just want solr providing this new feature and also want to
know whether any other users need this feature. if possible, I'd
like to participate in it.
sounds good. I would also be interested in such a functionality. I
think the first step would be to define a mapping between sql and
lucene queries (without actually implementing it) and check
whether and how this is possible.
It might be interesting to have a look at how jackrabbit is doing
it with
http://www.day.com/specs/jcr/2.0/6_Query.html

hi all,
we have used solr to provide searching service in many
products. I found for each product, we have to do some
configurations and query expressions.
our users are not used to this. they are familiar with
sql and they may describe like this: I want a query that
can search books whose title contains java, and I will
group these books by publishing year and order by
matching score and freshness, the weight of score is 2
and the weight of freshness is 1.
maybe they will be happy if they can use sql like
statements to convey their needs.
select * from books where title contains java group by
pub_year order by score^2, freshness^1
also they may like they can insert or delete documents
by delete from books where title contains java and
pub_year between 2011 and 2012.
we can define some language similar to sql and
translate the to solr query string such as
.../select/?q=+title:java^2 +pub_year:2011....
this may be equivalent to apache hive for hadoop.
It's not clear to me whether you are asking a question or
making a comment. Can you rephrase?
Thanks
Michael
