             Summary: SolrJ document object binding / BigDecimal
                 Key: SOLR-6539
                 URL: https://issues.apache.org/jira/browse/SOLR-6539
             Project: Solr
          Issue Type: Improvement
          Components: SolrJ
    Affects Versions: 4.10, 4.9, 4.10.1
            Reporter: Bert Brecht
             Fix For: 4.10.1


We are using BigDecimals in our application quite often for calculating. We store our values typically as java primitives (int, long/double, float) and using the DocumentObjectBinder (annotations based document object binding). 

Unfortunately, we must have exactly the type given in solr schema for type used as field/accessor. We found out, that the following patch would allow us to define BigDecimal as type as we just use BigDecimal as a type in our mapped POJO. This would help to make the mapping more powerful without loosing anything.
