Munendra S N commented on SOLR-11758:
-------------------------------------
Adding further details to explain the need for this.
I wanted to boost some documents by fixed value if they match some condition
{code:java}
if(and(query($qq1),query($qq2)),500,0)
{code}
Here, problem was that even when document matched these condition it was not
getting boosted. Even though query($qq1) and query($qq2) both returned non-zero
positive values (both values were < 1).
In this case, I could have also used *exists* which would solve but I wanted to
know the reason for such behavior.
On debugging, I found that *FloatDocValues* which is base class for
*QueryDocValues* doesn't implement *boolVal* method, hence, *boolVal* of
*FunctionValues* is called.
Ideally, *FloatDocValues* should have an implementation to override boolValue
like how it is done in *DoubleDocValues*.

> In case of *DoubleDocValues*, *boolVal(int doc)* has been implemented but
> this is missing in case *FloatDocValues*.
> *Impact*: For any DocValues which extends *FloatDocValues* and doesn't
> implement *boolVal(int doc)*, parent *boolVal* in FucntionValues would be
> called.
> boolVal implementation in FunctionValues
> {code:java}
> @Override
> public boolean boolVal(int doc) throws IOException {
> return intVal(doc) != 0;
> }
> {code}
> Let me know if I can work on it
