Apache SOLR using the SOLRJ Operation Index Library

SOLRJ is a relatively basic client tool for the SOLR Search server, which makes it very easy to interact with the SOLR search server. The most basic function is to manage SOLR indexes, including additions, updates, deletions, and queries. For some of the more basic applications, using SOLJ is basic enough, and you can easily interact with the SOLR search server by using the SOLRJ API to achieve basic management functionality for SOLR. If your application is more complex, you can extend the SOLRJ to meet your needs.

To manipulate the index library using SOLRJ:
