Adrien Grand commented on LUCENE-8565:
--------------------------------------

I like the idea. One thing that I'm wondering is whether some users are going 
to get caught by surprise if they rely on this limitation to prevent their 
users from searching other fields than the ones that are configured on the 
parser (since the default flag enables all operators).

> SimpleQueryParser to support field filtering (aka Add field:text operator)

> SimpleQueryParser lacks support for the `field:` operator for creating 
> queries which operate on fields other than the default field. Seems likeĀ one 
> can either get the parsed query to operate on a single field, or on ALL 
> defined fields (+ weights). No support for specifying `field:value` in the 
> query.
> It probably wasn't forgotten, but rather left out for simplicity, but since 
> we are using this QP implementation more and more (mostly through 
> Elasticsearch) we thought it would be useful to have it in.
> Seems like this is not too hard to pull off and I'll be happy to contribute a 
> patch for it.
