This also contains change were {{objectValue(doc)}} calls {{floatValue(doc)}} 
which returns default value if {{exists(doc)}} returns {{false}} but previously 
{{objectValue(doc)}} used to return {{null}} exists returned false even if 
default value is specified (in pure lucene case, there will always be default 
value). If this is expected change/fix should  we document the  change in 
behavior?

Above change resolves LUCENE-8908. Also, I wanted to share this

 which is from Solr's perspective as {{query}} could be used even without 
default value.

Just sharing my thoughts, please free to ignore if it doesn't apply here

Thanks a lot - i had not fully grasped the approximation mechanism and the 
{{TPI. asDocIdSetIterator(tpi)}} implementation.

I uploaded an updated patch.
