[jira] [Commented] (SOLR-6539) SolrJ document object binding / BigDecimal
[ https://issues.apache.org/jira/browse/SOLR-6539?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17736266#comment-17736266 ]
Yuntong Qu commented on SOLR-6539:
----------------------------------
Curious to if this issue is still active. It seems that to index high precision number, the workaround would be to create a custom schema, or index as string.

> 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.
