stored=true vs stored=false, in terms of storage

[Pramod Negi <ne...@gmail.com>]

Hi,

I am using Solr and I have one doubt.

If any field has stored=false, does it mean that this fields is stored in
disk and not in main memory. and this will be loaded whenever asked.


The scenario I would like to handle this, In my case there are lots of
information which I need to show when debugQuery=true, so i can take the
latency hit on debugQuery=true.

Can i save all the information in a field with "indexed=false" and
"stored=true".

And how do normally DebugInformation is saved

You can consider DocValues as well. There you can control whether they ever 
use heap memory or only file space.

See:

Hello!

Stored fields, the one with stored=true, mean that the original value
of the field is stored and can be retrieved with the document in
search results. Fields marked as stored=false can't be retrieved
during searching. That is the difference.
