Description

In solr 4.10.0 queries that request dynamic fields by passing in a fl=*_exact parameter do not return any fields. This appears to only be a problem when requesting wildcarded fields via SolrJ (BinaryResponseWriter). Looks like this may have been introduced via https://issues.apache.org/jira/browse/SOLR-5968

With Solr 4.10.0 - I downloaded the binary and set up the example:

cd example
java -jar start.jar
java -jar post.jar solr.xml monitor.xml

In a browser, if I request

http://localhost:8983/solr/collection1/select?q=*:*&wt=json&indent=true&fl=*d

All is well with the world:

{
"responseHeader": {
"status": 0,
"QTime": 1,
"params": {
"fl": "*d",
"indent": "true",
"q": "*:*",
"wt": "json"
}
},
"response": {
"numFound": 2,
"start": 0,
"docs": [
{
"id": "SOLR1000"
},
{
"id": "3007WFP"
}
]
}
}

However if I do the same query with SolrJ (groovy script)

@Grab(group = 'org.apache.solr', module = 'solr-solrj', version = '4.10.0')

import org.apache.solr.client.solrj.SolrQuery
import org.apache.solr.client.solrj.impl.HttpSolrServer

HttpSolrServer solrServer = new HttpSolrServer("http://localhost:8983/solr/collection1")
SolrQuery q = new SolrQuery("*:*")
q.setFields("*d")
println solrServer.query(q)

No fields are returned:

{responseHeader={status=0,QTime=0,params={fl=*d,q=*:*,wt=javabin,version=2}},response={numFound=2,start=0,docs=[SolrDocument{}, SolrDocument{}]}}

Issue Links

• is a clone of: SOLR-6497 Solr 4.10 returning SolrDocument instances with empty map when dynamic fields are requested
• is broken by: SOLR-5968 BinaryResponseWriter fetches unnecessary stored fields when only pseudo-fields are requested
