Class AsyncBuildSuggestComponent

  • All Implemented Interfaces:
    org.apache.lucene.util.Accountable, org.apache.solr.core.SolrInfoMBean, org.apache.solr.spelling.suggest.SuggesterParams, org.apache.solr.util.plugin.NamedListInitializedPlugin, org.apache.solr.util.plugin.SolrCoreAware
    public class AsyncBuildSuggestComponent
extends org.apache.solr.handler.component.SearchComponent
implements org.apache.solr.util.plugin.SolrCoreAware, org.apache.solr.spelling.suggest.SuggesterParams, org.apache.lucene.util.Accountable
    Originally taken from SuggestComponent and modified, this class provides a SearchComponent that builds SolrSuggester objects asynchronously to avoid blocking search requests or increasing startup time of the servlet container.
