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.
Compiling the server
git clone https://github.com/apache/lucene-solr cd lucene-solr git checkout ea2c8ba ant compile cd solr ant server
Building the collection
We followed Exercise 2 from the Solr Tutorial. The attached file (home.zip) gives the contents of folder /tmp/home that you will obtain by following the steps below:
mkdir -p /tmp/home echo '<?xml version="1.0" encoding="UTF-8" ?><solr></solr>' > /tmp/home/solr.xml
In one terminal start a Solr instance in foreground:
./bin/solr start -f -p 8983 -s /tmp/home
In another terminal, create a collection of movies, with no shards and no replication, and initialize it:
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.jsonSteps to reproduce Use a Linux machine.

Description
Requesting the following URL causes Solr to return an HTTP 500 error response:
http://localhost:8983/solr/films/select?facet.query=&q={!frange%20l=10%20u=100}boost({!v=+},3)
The error response seems to be caused by the following uncaught exception:
ERROR (qtp689401025-23) [ x:films] o.a.s.s.HttpSolrCall null:java.lang.NullPointerException at org.apache.lucene.queries.function.FunctionScoreQuery.rewrite(FunctionScoreQuery.java:109) at org.apache.lucene.search.IndexSearcher.rewrite(IndexSearcher.java:667) at org.apache.lucene.queries.function.valuesource.QueryValueSource.createWeight(QueryValueSource.java:75) at org.apache.solr.search.function.ValueSourceRangeFilter.createWeight(ValueSourceRangeFilter.java:105) at org.apache.solr.search.SolrConstantScoreQuery$ConstantWeight.<init>(SolrConstantScoreQuery.java:94) at org.apache.solr.search.SolrConstantScoreQuery.createWeight(SolrConstantScoreQuery.java:119) at org.apache.lucene.search.IndexSearcher.createWeight(IndexSearcher.java:717) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:443) at org.apache.solr.search.SolrIndexSearcher.buildAndRunCollectorChain(SolrIndexSearcher.java:200) at org.apache.solr.search.SolrIndexSearcher.getDocListNC(SolrIndexSearcher.java:1604) at org.apache.solr.search.SolrIndexSearcher.getDocListC(SolrIndexSearcher.java:1420) at org.apache.solr.search.SolrIndexSearcher.search(SolrIndexSearcher.java:567) at org.apache.solr.handler.component.QueryComponent.doProcessUngroupedSearch(QueryComponent.java:1434) at org.apache.solr.handler.component.QueryComponent.process(QueryComponent.java:373) at org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:298) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:199) at org.apache.solr.core.SolrCore.execute(SolrCore.java:2559) at org.apache.solr.servlet.HttpSolrCall.execute(HttpSolrCall.java:711) at org.apache.solr.servlet.HttpSolrCall.call(HttpSolrCall.java:516) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:394) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:340) [...]
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].
