----------------------------------
Labels: pull-request-available (was: )
> Improve Combined Query Feature Documentation
> ---------------------------------------------
>
> Key: SOLR-18100
> URL: https://issues.apache.org/jira/browse/SOLR-18100
> Project: Solr
> Issue Type: Improvement
> Components: vector-search
> Reporter: ilariapet
> Priority: Minor
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> I investigated the Combined Query feature to write a blog post about it, and
> I found a few aspects of the documentation that, are unclear and should be
> improved (I can take care of addressing them).
> In particular:
> *Configuration section*
> The part that explains the configuration is not very clear.
> {{maxCombinerQueries}} is a parameter that must be specified in the
> {{{}searchComponent{}}}, not in the handler.
> The search component is shown only to explain the custom algorithm part, so
> it is not obvious that it is mandatory even when using the default algorithm.
> Otherwise, a {{NullPointerException}} is thrown.
> *Solr Standalone - Distributed Search*
> As explained here
> ([https://solr.apache.org/guide/solr/latest/deployment-guide/user-managed-distributed-search.html#allowurls-parameter])
> {{allowUrls}} is automatically configured for SolrCloud, but it requires
> explicit configuration for user-managed setups.
> Therefore, when executing the combined query *without* starting Solr with:
> {code:java}
> --jvm-opts "-Dsolr.security.allow.urls=http://localhost:8983/solr/"; {code}
> the following error is returned:
> {code:java}
> "errorClass": "org.apache.solr.common.SolrException",
> "msg": "The 'shards' parameter value 'http://localhost:8983/solr/test'
> contained value(s) not allowed: URL http://localhost:8983/solr/test is
> neither a live node of the cluster nor in the configured 'allowUrls' []. Set
> -Dsolr.security.allow.urls.enabled=false to disable URL allow-list
> checks."{code}
> This should be explicitly mentioned in the documentation.
> *Custom plugin section*
> This section is not detailed enough to clearly explain how it should be used,
> especially for users who are not experienced with Solr.
