Matthias Herrmann commented on SOLR-4835:
-----------------------------------------
I found a workaround for this issue by using lucene OR operator. When the query
looks like:
[http://localhost:8983/solr/collection1/select?q=belkin+OR+\{!join+from=id+to=id\}belkin&defType=lucene&wt=json&indent=true&hl=true&hl.fl=*]
The results are as expected.
> highlighting in combination with join does not work in solr 4.0 - 4.2

> Key: SOLR-4835
> URL: https://issues.apache.org/jira/browse/SOLR-4835
> Project: Solr
> Issue Type: Bug
> Components: highlighter, query parsers
> Affects Versions: 4.0-ALPHA
> Reporter: Matthias Herrmann
> Labels: documentation
>
> I need to highlight results based on a query that contains a join operation.
> I want to highlight docs that occur in the "to" set which is in my
> understanding the final result set of the join operation.
> I made a simple example by indexing example/exampledocs/*.xml which ships
> with standard Solr distribution. Having these documents indexed to the
> example server I run the following query:
> [http://localhost:8983/solr/collection1/select?q=belkin&defType=lucene&wt=json&indent=true&hl=true&hl.fl=*
> ]
> In the query result the section "highlighting" looks like:
> {code}
> "highlighting":{
> "F8V7067-APL-KIT":{
> "name":["<em>Belkin</em> Mobile Power Cord for iPod w/ Dock"],
> "manu_id_s":["<em>belkin</em>"],
> "manu":["<em>Belkin</em>"]},
> "IW-02":{
> "manu_id_s":["<em>belkin</em>"],
> "manu":["<em>Belkin</em>"]}}
> {code}
> So highlighting works fine. BUT when running this query:
> [http://localhost:8983/solr/collection1/select?q=\{!join+from=id+to=id\}belkin&defType=lucene&wt=json&indent=true&hl=true&hl.fl=*]
> In the query result the section "highlighting" looks like:
> {code}
> "highlighting":{
> "F8V7067-APL-KIT":{},
> "IW-02":{}}
> {code}
> As you can see highlighting does not work in combination with join. Is this a
> bug or am I missing something?
