Hello David,
Thank you for your reply.
It was very hard but finally I discovered how to reproduce it. I thought of
issuing an issue but wasn't sure about the components and priority.
I used the "tech products" configset, with the following changes:
1. Added <field name="_nest_path_" type="_nest_path_" /><fieldType
name="_nest_path_" class="solr.NestPathField" />
2. Added <field name="text_en" type="text_en" indexed="true" stored="true"
termVectors="true" termOffsets="true" termPositions="true" required="false"
multiValued="true" />
Than I inserted one document with a nested child e.g.
{id:"abc_1", utterances:{id:"abc_1-1", text_en:"Solr is great"}}
To reproduce:
Do a search with surround and unified highlighter:
hl.fl=text_en&hl.method=unified&hl=on&q=%7B!surround%7Dtext_en%3A4W("solr"%2C"great")
Now, try to update the parent e.g. {id:"abc_1", categories_i:{add:1}}
Important: it happens only when "id" contains underscore characters! If you'll
use "abc-1" it would work.
Thanks in advance,
Ronen.

Subject: Re: Atomic Update (nested), Unified Highlighter and Lazy Field Loading
=> Invalid Index
Hello Ronen,
Can you please file a JIRA issue? Some quick searches did not turn anything
up. It would be super helpful to me if you could list a series of steps with
Solr out-of-the-box in 8.8 including what data to index and query. Solr
already includes the "tech products" sample data; maybe that can illustrate the
problem? It's not clear if nested schema or nested docs are actually required
in your example. If you share the JIRA issue with me, I'll chase this one down.
