org.eclipse.smila.integration.solr.SolrIndexPipelet
Description
This pipelet integrates Apache Solr's HTTP REST API (http://wiki.apache.org/solr/SearchHandler?action=show&redirect=StandardRequestHandler and http://wiki.apache.org/solr/UpdateXmlMessages ) for adding and deleting records in an Solr index. Therefore it is now possible to build large volume search applications by basing them on SMILA and deploying Solr for coping with large indices which are not manageable on one node because of their large size which exceeds the limits of the node's file system.
Note: Currently this pipelet supports Solr 1.4. The integration of features added with the release of Solr 1.5 will be done in near future.
