Easynet. SOLR (http://easynet.codeplex.com) is a SOLR (http://lucene.apache.org/solr) C # client developed by myself. It has the following features: 1. Support for SOLR 3.1 (not compatible with SOLR 1.4.x) 2. By default, SOLR's most efficient javabin protocol is suppo

Lucene files to improve search performance. It is usually better to perform optimization after the index is complete. If updates are frequent, you should optimize them when the usage is low. An index can run normally without optimization. Optimization is a time-consuming process. Delete can be specified by ID or query. Deleting by ID will delete documents with the specified ID. Deleting by query will delete all documents returned by the query. A ty
