Yonik Seeley commented on SOLR-334:
-----------------------------------
So I recently added a nested query parser... it's useful to be able to allow
the client to specify query parts but not know about them.
So a client could send bf=<!query v=$dateboost> to add a date boost, but the
actual date boost query could be configured as a default on the server:
dateboost=<!func>recip(rord(datefield,1,1000,1000))
I'm finding the local params stuff very useful, but I hate the fact that when I
type the following URL in firefox, it transforms all the special chars. It
makes it very hard to edit (I use a browser a lot for testing). Also, < would
need to be escaped in any XML config too.
Example: I type in
http://localhost:8983/solr/select?q=<!dismax qf='title^10 body'>foo
But then firefox transforms it to
http://localhost:8983/solr/select?q=%3C!dismax%20qf='title^10%20body'%3Efoo
So while things are still changeable (before a release), is this really the
right syntax?
We could alternately go with [! which doesn't have this problem (and wouldn't
have to be escaped in XML config either).
So it could look like:
http://localhost:8983/solr/select?q=[!dismax qf='title^10 body']foo
Which firefox changes to
http://localhost:8983/solr/select?q=[!dismax%20qf='title^10%20body']foo
Thoughts?

> One should be able to optionally specify an alternate query syntax on a
> per-query basis

> Many benefits, including avoiding the need to do query parser escaping for
> simple term or prefix queries.
> Possible Examples:
> fq=<!term field="myfield">The Term
> fq=<!prefix field="myfield">The Prefix
> q=<!qp op="AND">a b
> q=<!xml><?xml...> // lucene XML query syntax?
