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 and reproducing the bug
We followed Exercise 2 from the Solr Tutorial.
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.json curl -v “URL_BUG”Please check the issue description below to find the “URL_BUG” that will allow you to reproduce the issue reported.

Description
Requesting the following URL causes Solr to return an HTTP 500 error response:
http://localhost:8983/solr/films/select?mm=%3C&defType=edismax&q=fq=field(id,1)
The error response seems to be caused by the following uncaught exception:
java.lang.ArrayIndexOutOfBoundsException: 0 at org.apache.solr.util.SolrPluginUtils.calculateMinShouldMatch(SolrPluginUtils.java:683) at org.apache.solr.util.SolrPluginUtils.setMinShouldMatch(SolrPluginUtils.java:641) at org.apache.solr.util.SolrPluginUtils.setMinShouldMatch(SolrPluginUtils.java:660) at org.apache.solr.search.ExtendedDismaxQParser.parseOriginalQuery(ExtendedDismaxQParser.java:415) at org.apache.solr.search.ExtendedDismaxQParser.parse(ExtendedDismaxQParser.java:173) at org.apache.solr.search.QParser.getQuery(QParser.java:173) at org.apache.solr.handler.component.QueryComponent.prepare(QueryComponent.java:158) at org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:272) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:199) at org.apache.solr.core.SolrCore.execute(SolrCore.java:2559)
The mm parameter is given as ‘<’. It is (after some string mangling) split into sub-strings separated by ‘<’, putattively giving the left-hand and right-hand argument of the operator. In the example, there are no such arguments, so the resulting array “parts” is empty (cf. String.split documentation). But we immediately try to access parts[0], leading to an AIOOBE.
To set up an environment to reproduce this bug, follow the description in the ‘Environment’ field.
