>             Project: Solr
>          Issue Type: Bug
>          Components: search
>    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.

> {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}

> Requesting the following URL causes Solr to return an HTTP 500 error response:
> {noformat}
> http://localhost:8983/solr/films/select?uf=fl=gen*,id&defType=edismax
> {noformat}
> The error response seems to be caused by the following uncaught exception:
> {noformat}
> java.lang.RuntimeException: dynamic field name must start or end with *
> at org.apache.solr.search.ExtendedDismaxQParser$DynamicField.<init>(ExtendedDismaxQParser.java:1610)
> {noformat}
> The DynamicField parser throws this RuntimeException to tell the user that the given query is invalid. Sadly, the exception is never caught, so it manifests as a 500 error instead of a 400 error.
