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.
Reporter: Johannes Kloos
Requesting the following URL causes Solr to return an HTTP 500 error response:
{noformat}
http://localhost:8983/solr/films/select?fq={!frange%20l=10%20u=100}or_version_s,directed_by
{noformat}
The error response seems to be caused by the following uncaught exception:
{noformat}

Sadly, I can't understand the logic of this code well enough to give any
insights.
