Subject Re: docValues
Date Fri, 24 Nov 2017 17:15:02 GMT
Thank you very much for your answer, Shawn.

That is it, I was looking for another way to include fields non docValues
to the filtered result documents.
I can enable docValues to other fields and reindex all if necessary. I will
tell you about the use case, because I am not sure  that I am on the right
track.

As I said before, I am using Streaming Expressions to deal with different
collections. Up to this moment, it is decided that we will use this
approach.

The goal is to provide our users a web interface where they can make some
queries. The backend will get Solr data using the Streaming Expressions
rest api and will return rolled up data to the frontend, which will display
some charts and aggregated data.
After that, the end user may want to have data used to generate this
aggregated information (not all fields of the filtered documents, but the
fields used to aggregate information), combined with some other fields
(title, description of document for example) which are not docValues. As
you said I need to add docValues to then. My question is, isnĀ“t it to
expensive in terms of memory consumption to enable docValues on fields that
I dont need to facet, search etc?

I think that to reconstruct a standard query that achieves the results from
a complex Streaming Expression is not simple. This is why I want to use the
same query used to make analysis, to return full data via export handler.

I am sorry if this is so much confusing.

Thank you,
