Yes. But being inside solr ( I mean code getting executing via Custom
function ), do we have option to read the other solr documents in a easy
way.

Hello,
It sounds either like classic denormalization or (little bit slow and
cumbersome) result transformer [subquery].

Hi,
I am using SOLR 7.5 in the cloud mode.
I want to create a custom function similar to 'strdist' that works on
multivalued fields (multiValued=true) and finds the highest matching score.
Yes, I know the potential performance issues, but in my usecase this would
bring a huge benefit.

Hi,
I have been looking around on the web for information on sorting by a

so old that I suspect it's outdated. What I want to do is the following:
I have a field "fingerprint" in my schema that contain

are used by Solr sometimes.

I'm unable to do so. It seems that the tokenizer messes this up and only a

In Solr 4.9 there is a feature called RankQueries, that allows you to
plugin your own ranking collector. So, if you wanted to write a
ranking/sorting collector that used a thread per segment, you could cleanly
plug it in.

Can you please describe what your end goal is in writing a custom

your funciton?
In general, accessing stored field values for indexed documents ca be

attribute "name"

Got it! Just for you to share ... and maybe for inclusion in the Java
API docs of ValueSource :)
For sorting one needs to implement the method
public double doubleVal(int) of the class ValueSource
then it works like a charm.

your ValueSource can wrap the score from the other query using a

I use the following 2 components in ranking documents:
