[jira] [Commented] (SOLR-14382) delegating search component

["Christine Poerschke (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-14382?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17074771#comment-17074771 ] 

Christine Poerschke commented on SOLR-14382:
--------------------------------------------

We have a use case for two distinct {{QueryComponent}} customisations for field vs. score sorted searches.

This could be supported via two different search handlers e.g.

{code}
<searchComponent name="queryFoo" class="com.company.team.FooQueryComponent"/>

<requestHandler name="/selectFoo" class="solr.SearchHandler">
  <arr name="components">
    ...
    <str>queryFoo</str>
    ...
  </arr>
  ...
</requestHandler>

<searchComponent name="queryBar" class="com.company.team.BarQueryComponent"/>

<requestHandler name="/selectBar" class="solr.SearchHandler">
  <arr name="components">
    ...
    <str>queryBar</str>
    ...
  </arr>
  ...
</requestHandler>
{code}

but this would introduce complexity on the client side i.e. the client needs to send to different end-points depending on the type of search.

As an alternative to this we think a custom 'query component multiplexer' could work e.g.

{code}
<searchComponent name="query" class="com.company.team.QueryComponentMultiplexer"/>
{code}

replaces the default {{org.apache.solr.handler.component.QueryComponent}} and switches behaviour depending on the search parameters.
