David Smiley commented on SOLR-17085:
-------------------------------------

What is the use-case where this is needed?  I could imagine instead a tweak in 
which we indicate a parameter name that holds the query, defaulting to "q" but 
you could use whatever you want.  That would be way more flexible than assuming 
exactly one "fq" param as I see in your PR.

> ([PR-2098|https://github.com/apache/solr/pull/2098])
> This ticket introduces a new QueryElevation related feature. 
> Currently, QueryElevationComponent is implemented and can be used to 
> configure/customize the top results for a given query, depending on the field 
> query "{color:#0747a6}*q*{color}" .
> This ticket suggests an extension of this feature that allows users to 
> configure the top results,  based on the Filter Query field 
> "{*}{color:#0747a6}fq{color}{*}" as well.
> Below is an example query.
> !image-2023-11-27-16-58-06-472.png!
> Based on the "{*}{color:#0747a6}fq{color}{*}" field value, we would get, as 
> top results, regardless of the normal Lucene scoring, the elements configured 
> in *{color:#0747a6}elevate.xml{color}* schema.
> {code:java}
>   <query text="cat:electronics"> 
>     <doc id="TWINX2048-3200PRO" /> 
>     <doc id="VDBDB1A16" />   
>     <doc id="EN7800GTX/2DHTV/256M" />
>   </query>{code}
> Instead of having a classic value for the "{*}{color:#0747a6}text{color}{*}" 
> field in the {color:#0747a6}*<query>*{color} tag in the code snippet above, 
> introducing a Filter Query expression allows to configure top results for 
> queries having the an "{*}{color:#0747a6}fq{color}{*}" field value containing 
> "{*}{color:#0747a6}cat:electronics{color}{*}", and therefore, they will be 
> returned in the top of the results list.
