Have a large string/text field but be able to use export handler too

[Ufuk YILMAZ via users]

I am a fan of the export handler so I try to have docValues in all my 
fields to be able to export them, if it's an analyzed field, I just make 
a companion copyField that stores string and has docValues.

Today I came across a situation that I couldn't solve. I have a field 
that stores a very long string. If I simply configure it with:

`indexed="false" stored="false" docValues="true" 
useDocValuesAsStored="true"`

when indexing it throws an error saying something like:

`DocValuesField "data" is too large, must be <= 32766`

then I thought of storing it as binary:

`<field name="data" type="binary" indexed="false" stored="false" 
docValues="true" useDocValuesAsStored="true"/>`

I was able to index the large field this way. However, when I called the 
export handler, it threw an error saying "field type must be one of 
these: int, long, string, SortableText..." which doesn't include 
"binary"

Then I tried making a stored string (type=string, stored=true, 
docValues=false) which worked for indexing, but not for the export 
handler due to lacking docValues (AI hallucinated that new Solr versions 
support exporting stored fields...)

So, is there a way to have a large field but also have the capability of 
using the export handler?
