Subject [jira] [Commented] (SOLR-7435) NPE in FieldCollapsingQParser
Date Mon, 04 May 2015 10:21:06 GMT

    [ https://issues.apache.org/jira/browse/SOLR-7435?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14526501#comment-14526501
] 

Markus Jelsma commented on SOLR-7435:
-------------------------------------

Hi [~joel.bernstein], can you try the following unit test?

{code}
  @Test
  public void testSOLR7435() throws Exception {
    for (int i = 0; i < 15000; i++) {
      String[] doc = {"id", String.valueOf(i) , "a_i", String.valueOf(random().nextInt(1)),
"b_i", String.valueOf(random().nextInt(1))};
      assertU(adoc(doc));
    }
    
    assertU(commit());
    
    ModifiableSolrParams params = new ModifiableSolrParams();
    params.add("q", "*:*");
    params.add("fq", "{!collapse field=a_i}");
    params.add("fq", "{!collapse field=b_i}");
    assertQ(req(params, "indent", "on"), "*[count(//doc)=0]");
  }
{code}

It fails on my machine using: ant test  -Dtestcase=TestCollapseQParserPlugin -Dtests.method=testSOLR7435
-Dtests.seed=2B7D48BE88DE05E7 -Dtests.slow=true -Dtests.locale=en_ZA -Dtests.timezone=America/Araguaina
-Dtests.asserts=true -Dtests.file.encoding=US-ASCII

> Not even sure it would work anyway, i tried to collapse on two distinct fields, ending
up with this:
