Set LucySearchEngine Properties

By default, Lucy looks for its search engine at http://localhost:8080/solr, which is the location of the default Lucy search engine, called LucySearchEngine. If this is not the Solr engine you want Lucy to use, then you will need to:

Copy LucySearchEngine.properties from escenic-home/engine/plugins/lucy/siteconfig/localconfig/com/escenic/lucy/LucySearchEngine.properties to escenic-config/com/escenic/lucy/LucySearchEngine.properties for editing.
Open the copied file for editing.
Set the solrURI property to point to the correct Solr engine location. For example:
```
solrURI=http://mysolrhost:8080/solr
```
Give the search engine instance a unique name by setting the name property. For example:
```
name=AnotherLucyInstance
```
Save the file and exit.
