Examples of org.exist.storage.IndexSpec

org.exist.storage.IndexSpec
Top class for index definitions as specified in a collection configuration or the main configuration file. The IndexSpec for a given collection can be retrieved through method {@link org.exist.collections.Collection#getIndexConfiguration(DBBroker)}. An index definition should have the following structure:
```
 <index index-depth="idx-depth"> <fulltext default="all|none" attributes="true|false"> <include path="node-path"/> <exclude path="node-path"/> </fulltext> <create path="node-path" type="schema-type"> </index> 
```
