>                 Key: SOLR-13179
>                 URL: https://issues.apache.org/jira/browse/SOLR-13179
>             Project: Solr
>          Issue Type: Bug
>      Security Level: Public(Default Security Level. Issues are Public) 
>    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
> 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]. The attached file ({{home.zip}}) gives the contents of folder {{/tmp/home}} that you will obtain by following the steps below:
> {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
> {noformat}
>            Reporter: Marek
>            Priority: Minor
>              Labels: diffblue, newdev
>             Fix For: master (9.0), 8.1

> Requesting the following URL causes Solr to return an HTTP 500 error response:

> 1. In org/apache/solr/search/ValueSourceParser.java[330] a variable query 'q' is assigned the value null, which is obtained from org/apache/solr/search/LuceneQParser.java[39], because a variable 'qstr' is the empty string.
> 2. In org/apache/solr/search/ValueSourceParser.java[332] the null value of 'q' is passed to function 'FunctionScoreQuery.boostByValue', which in turn leads to initialisation of member 'in' of org.apache.lucene.queries.function.FunctionScoreQuery to null at org/apache/lucene/queries/function/FunctionScoreQuery.java[56].
> 3. Later, during execution of the query, there is dereferenced the member 'in' (still having the null value) at org/apache/lucene/queries/function/FunctionScoreQuery.java[109].
