      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

      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].
