Undertake multiple and highly complex architecture projects involving multiple disciplines across impact multiple business units; lead, define and manage initiatives and projects to develop new architecture models (e.g. If you need to add a customized implementation, the streaming expressions plugin approach is better suited to add internal only functions. There may be use cases where you want to integrate with Solr using the SolrNet library instead of going through Sitecore Content Search API. So it (or rather lucene ) concentrates on purely indexing data. Example has been provided in sample_techproducts_configs to override content-type. 3. public class LatLonType extends AbstractSubTypeFieldType implements SpatialQueryable. SOLR-11266: default Content-Type override for JSONResponseWriter from _default configSet is removed. You put documents in it (called "indexing") via JSON, XML, CSV or binary over HTTP. (Ishan Chattopadhyaya, Munendra S N, Gus Heck) SOLR-13593 SOLR-13690 SOLR-13691: Allow to look up analyzer components by their SPI names in field type configuration.
