what is the meaning of Solr Instance

An solr-instance is something like an runtime-environment. It's an running solr service. U use Solr to work with lucene. Lucene are java libraries to create/access/... the fulltext index, no instance, no running system. To contact/use this indexed data (import/export/search/...) , you need an "mediator" or "agent" like solr. Solr can index or access the indexed data by using lucene.

Example: if you have an laptop or pc. So the running (linux/win) system is an instance, while the data from the systems is stored on hard disk.

Solr is comparable with the running system, lucene is comparable with the disk-dirver to store data on your system-drive.

To get an definition of what an instance is, check this: http://en.wikipedia.org/wiki/Instance_%28computer_science%29

How I can create Solr Instance

by starting the tomcat server, which runs the Solr J2EE component. So if your Solr is still configured, start the tomcat for starting/creating an solr-instance.
