----------------------------------
Summary: EmbeddedSolrServer has broken sorting with functions and
non-alphanumeric symbols in field names
Key: SOLR-8403
URL: https://issues.apache.org/jira/browse/SOLR-8403
Project: Solr
Issue Type: Bug
Affects Versions: 5.3.1
Reporter: Vasiliy Bout
We are trying to use EmbeddedSolrServer to test our Java code, that sends
queries to Solr server.
We have a number of non-alphanumeric characters in field names in our schema,
and such field names work fine for searching and sorting on both real Solr
server (via HttpSolrClient) and on EmbeddedSolrServer.
But when we make search query that has functions in sort clause, real server
handles these queries correctly while EmbeddedSolrServer throws exception.
Suppose, we have a field with name {{foo:bar}}. The following query works fine
with both real server and EmbeddedSolrServer:
{code}
solrClient.query(new SolrQuery("*:*").addSort("foo:bar", SolrQuery.ORDER.desc));
{code}
But when we try to use functions in sort clause, exception is thrown by
EmbeddedSolrServer (real server works correctly). For the following code:
{code}
solrClient.query(new SolrQuery("*:*").addSort("def(foo:bar,0)",
SolrQuery.ORDER.desc));
{code}
we get the following exception:
{noformat}
org.apache.solr.common.SolrException: sort param could not be parsed as a
query, and is not a field that exists in the index: def(foo:bar,0)

If we have a space character between function arguments:
{code}
solrClient.query(new SolrQuery("*:*").addSort("def(foo:bar, 0)",
SolrQuery.ORDER.desc));
{code}
we get different exception:
{noformat}

desc) in sort spec 'def(foo:bar, 0) desc', pos=12

Anyway, we have our tests failing with correctly written code that works on
real server. Please, make EmbeddedSolrServer to behave the same way as the real
Solr server.
