Description

Solr can't add flexible some plugins in the handler that means have to rewrite the self handle if you want to append new functional. Ex. Validation module

The plugin module can be setting in the solrconfig.xml, the default plugin can be request parameter that it is same as SolrPluginUtils.setDefaults behavior.

If customer want to add some new/common function, don't need write the self handler, only add a new plugin and configure it in the xml file.

Config XML format:
<requestHandler name="/select" class="solr.SearchHandler">
<plugin class="com.xxx.validateplugin.class" />
</requestHandler>
