---------------------------------------
Understood. Thanks for your input and sorry for wasting your time with this
non-issue
> Solrj QueryResponse results not presented in proper score order

> Key: SOLR-5929
> URL: https://issues.apache.org/jira/browse/SOLR-5929
> Project: Solr
> Issue Type: Bug
> Components: clients - java
> Affects Versions: 4.6.1
> Environment: Windows 7, Java 7
> Reporter: Chris Pilsworth
>
> It would appear that the results collection is sorting on the score as a
> string where there is an exponent.
> When searching for a term that returns two documents, one with a
> significantly smaller score than the other the results are returned
> *correctly* from solr directly.

> However, when read through the solrj client, the document with the lower

> order.
