Subject [jira] Created: (SOLR-1468) Solrj bug when using facet.missing
Date Sun, 27 Sep 2009 20:56:16 GMT
Solrj bug when using facet.missing
----------------------------------

                 Key: SOLR-1468
                 URL: https://issues.apache.org/jira/browse/SOLR-1468
             Project: Solr
          Issue Type: Bug
          Components: clients - java
    Affects Versions: 1.3
            Reporter: Tomasz Wrobel


Setting queryParams.setMissing("true") or queryParams.set(FacetParams.FACET_MISSING, "true")
in Solrj query parameters object results in an exception:
...
Caused by: org.apache.solr.common.SolrException: parsing error
    at org.apache.solr.client.solrj.impl.XMLResponseParser.processResponse(XMLResponseParser.java:139)

When "facet.missing" parameter is set to "true" Solr is returning response containing "int"
element with no "name", which possibly causes the Solrj parsing problem. Sample server response
may look like:

<lst name="genre">
    <int name="rock">5559</int>
    <int name="soul">5547</int>
    <int name="punk">5412</int>
    <int>0</int>
</lst>
