Scott Lindner created SOLR-6045:
-----------------------------------
Summary: atomic updates w/ solrj + BinaryRequestWriter aren't
working when adding multiple fields w/ same name in a single SolrInputDocument
Key: SOLR-6045
URL: https://issues.apache.org/jira/browse/SOLR-6045
Project: Solr
Issue Type: Bug
Affects Versions: 4.8
Environment: client & server both on 4.8
Reporter: Scott Lindner
I'm using the following code snippet:
{code}
HttpSolrServer srvr = new HttpSolrServer("HOST:8983/solr/foo-test");
SolrInputDocument sid = new SolrInputDocument();
sid.addField("id", "some_id");
Map<String, String> fieldModifier = Maps.newHashMap();
fieldModifier.put("set", "new_value1");
sid.addField("field1", fieldModifier);
Map<String, Object> fieldModifier2 = Maps.newHashMap();
fieldModifier2.put("set", "new_value2");
sid.addField("field1", fieldModifier2);
srvr.add(sid);
srvr.commit();
{code}
*NOTE*: the important part here is that I am using the same field name and
adding 2 values separately to the same solr document.
This produces the correct values in the index. Here is the output from
searching from the admin console:
{noformat}
"field1": [
"new_value1",
"new_value2"
]
{noformat}
However if I modify the above code to have the following lines after creating
the SolrServer:
{code}
srvr.setRequestWriter(new BinaryRequestWriter());
srvr.setParser(new BinaryResponseParser());
{code}
Then the values that are returned are incorrect:
{noformat}
"field1": [
"{set=new_value1}",
"{set=new_value2}"
]
{noformat}
This also behaves the same if I use the CloudSolrServer as well.
If I modify my code to look like the following:
{code}
Map<String, List<String>> fieldModifier = Maps.newHashMap();
fieldModifier.put("set", Lists.newArrayList("new_value1",
"new_value2"));
sid.addField("field1", fieldModifier);
{code}
Then this *does* work with the BinaryRequestWriter. So this seems to be an
issue when calling addField() with the same name multiple times.
In the process of debugging this I think I also uncovered a few other similar
issues but I will file separate bugs for those.
