Subject [jira] Resolved: (SOLR-1815) SolrJ doesn't preserve the order of facet queries returned from solr
Date Sun, 14 Mar 2010 05:57:27 GMT

     [ https://issues.apache.org/jira/browse/SOLR-1815?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yonik Seeley resolved SOLR-1815.
--------------------------------

       Resolution: Fixed
    Fix Version/s: 1.5

Committed.  I almost didn't add a CHANGES entry this is so trivial... if others agree we could
just remove and lessen the amount of noise people need to read through.

> Using Solrj, I wanted to sort the response of a range query based on some specific labels.
For instance, using the query:
> {noformat}
> facet=true
> &facet.query={!key= Less than 100}[* TO 99]
> &facet.query={!key=100 - 200}[100 TO 200]
> &facet.query={!key=200 +}[201 TO *]
> {noformat}
> I wanted to display the response in the following order:
> {noformat}
> Less than 100 (x)
> 100 - 200 (y)
> 201 + (z)
> {noformat}
> independently on the values of x, y, z which are the numbers of the retrieved documents
for each range.
> While Solr itself produces correctly the desired order (as specified in my query), SolrJ
doesn't preserve it. 
> RE: Yonik, a solution could be just to change
> {code}
> _facetQuery = new HashMap<String, Integer>();
>     ...to...
> _facetQuery = new Linked HashMap<String, Integer>();
> {code}
