The problematic query ( {{?fq=\{!frange l=10 u=100}or_version_s,directed_by}} )
specifies two value sources separated by a comma
({{or_version_s,directed_by}}). These are parsed as a {{VectorValueSource}}
embedding the two individual ValueSources corresponding to the two fields (see
[FunctionQParser.java:115|https://github.com/apache/lucene-solr/blob/master/solr/core/src/java/org/apache/solr/search/FunctionQParser.java#L115]).

> Key: LUCENE-8674
> URL: https://issues.apache.org/jira/browse/LUCENE-8674
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/query/scoring
> Affects Versions: master (9.0)
> Environment: h1. Steps to reproduce
> * Use a Linux machine.
> * Build commit {{ea2c8ba}} of Solr as described in the section below.
> * Build the films collection as described below.
> * Start the server using the command {{./bin/solr start -f -p 8983 -s
> /tmp/home}}
> * Request the URL given in the bug description.
> h1. Compiling the server
> {noformat}
> git clone https://github.com/apache/lucene-solr
> cd lucene-solr
> git checkout ea2c8ba
> ant compile
> cd solr
> ant server
> {noformat}
> h1. Building the collection and reproducing the bug
> We followed [Exercise
> 2|http://lucene.apache.org/solr/guide/7_5/solr-tutorial.html#exercise-2] from
> the [Solr
> Tutorial|http://lucene.apache.org/solr/guide/7_5/solr-tutorial.html].
> {noformat}
> mkdir -p /tmp/home
> echo '<?xml version="1.0" encoding="UTF-8" ?><solr></solr>' >
> /tmp/home/solr.xml
> {noformat}
> In one terminal start a Solr instance in foreground:
> {noformat}
> ./bin/solr start -f -p 8983 -s /tmp/home
> {noformat}
> In another terminal, create a collection of movies, with no shards and no
> replication, and initialize it:
> {noformat}
> bin/solr create -c films
> curl -X POST -H 'Content-type:application/json' --data-binary '{"add-field":
> {"name":"name", "type":"text_general", "multiValued":false, "stored":true}}'
> http://localhost:8983/solr/films/schema
> curl -X POST -H 'Content-type:application/json' --data-binary
> '{"add-copy-field" : {"source":"*","dest":"_text_"}}'
> http://localhost:8983/solr/films/schema
> ./bin/post -c films example/films/films.json
> curl -v “URL_BUG”
> {noformat}
> Please check the issue description below to find the “URL_BUG” that will
> allow you to reproduce the issue reported.
