Gautam Worah commented on LUCENE-9956:
--------------------------------------
Here is why I need just the baseQuery and drill down queries from a
{{DrillDownQuery}} object.
I have an initial {{DrillDownQuery}} that I construct by parsing the user's
{{BooleanQuery}} and add custom {{subQuery}} s to it using the {{add(String
dim, Query subQuery)}} API.
Then later on, I try to optimize the base {{BooleanQuery}} (remove some terms)
and create a new {{DrillDownQuery}} object and add the original \{{subQuery}} s
back.
Can we make rewrite() do this? Yes
Pros: Does not expose the {{baseQuery}} and limits the access
Cons:
1. {{rewrite}} returns a so to say combined form of the {{DrillDownQuery}}.
The user will have to again parse the first BQ clause and get the {{baseQuery}}
then parse all the remaining clauses and get the \{{subQuery}}s.
2. Using the {{rewrite}} function to get the {{baseQuery}} is a bit non
intuitive

> Project: Lucene - Core

> Priority: Trivial

> It would be great if users could access the baseQuery of a DrillDownQuery. I
> think this can be useful for folks who want to access/test the clauses of a
> BooleanQuery (for example) after they've already wrapped it into a
> DrillDownQuery.
>
> Currently the {{Query getBaseQuery()}} method is package private by default.
> If this proposed change does not make sense, or if this change breaks the
> semantic of the class, I am happy to explore other ways of doing this!
