    Returns:
    
    a CloseableIterable object.
  - getSearcherFactory
```
public org.apache.lucene.search.SearcherFactory getSearcherFactory()
```
    Gets the searcher factory associated to this index
  - getTotalShards
```
public int getTotalShards()
```
    Gets the number of shards (sub-directories) in this index.
    
    Specified by:
    
    getTotalShards in interface OracleIndex<T extends Element>
  - isAutoIndex
```
public boolean isAutoIndex()
```
    Returns true if this is an auto index
  - put
```
public void put(String key,
       Object value,
       T element)
```
    Indexes an element by a key and a value.
    
    Specified by:
    
    put in interface Index<T extends Element>
    
    Parameters:
    
    key - the key to index the element by.
    
    value - the value to index the element by.
    
    element - the element to index.
  - put
```
public void put(String key,
       Object value,
       T element,
       OracleIndexWriter[] indexWriters)
```
    Indexes an element by a key and a value. Using an array of OracleIndexWriter for all the sub-directories in the text index reduce the number of open/commit/close operations to Apache Lucene. The user is responsible of calling the commit operation on each index writer so the changes executed by this operation are persisted into the text index.
    
    Parameters:
    
    key - the key to index the element by.
    
    value - the value to index the element by.
    
    element - the element to index.
    
    indexWriters - if not null, the cache of indexWriters to use, this avoids opening/closing index writers at flush time, but locks writing operations over the index.
  - query
```
public final CloseableIterable<T> query(String key,
                         Object value)
```
    Query for all the elements satisfying the specified K/V property within the index
    
    Specified by:
    
    query in interface Index<T extends Element>
    
    Parameters:
    
    key - the key of the K/V property
    
    value - the value object of the K/V property
    
    Returns:
    
    a CloseableIterable object.
  - query
```
public final CloseableIterable<T> query(String key,
                         Object value,
                         boolean useWildcards)
```
    Query for all the elements satisfying the specified K/V property within the index
    
    Specified by:
    
    query in interface OracleIndex<T extends Element>
    
    Parameters:
    
    key - the key of the K/V property
    
    value - the value object of the K/V property
    
    useWildcards - specifies if wild cards can be used in the value object.
    
    Returns:
    
    a CloseableIterable object.
  - remove
```
public void remove(String key,
          Object value,
          Class dtValue,
          T element,
          OracleIndexWriter[] indexWriters)
```
    Removes an element indexed by a particular key/value. Using an array of OracleIndexWriter for all the sub-directories in the text index reduce the number of open/commit/close operations to Apache Lucene. The user is responsible of calling the commit operation on each index writer so the changes executed by this operation are persisted into the text index.
    
    Parameters:
    
    key - the key of the indexed element.
    
    value - the value of the indexed element.
    
    dtValue - the data type class of the indexed element.
    
    element - the element to remove given the key/value pair.
    
    indexWriters - if not null, the cache of indexWriters to use, this avoids opening/closing index writers at flush time, but locks writing operations over the index.
  - remove
```
public void remove(String key,
          Object value,
          T element)
```
    Removes an element indexed by a particular key/value.
    
    Specified by:
    
    remove in interface Index<T extends Element>
    
    Parameters:
    
    key - the key of the indexed element.
    
    value - the value of the indexed element.
    
    element - the element to remove given the key/value pair.
  - remove
```
public void remove(String key,
          Object value,
          T element,
          OracleIndexWriter[] indexWriters)
```
    Removes an element indexed by a particular key/value.
    
    Parameters:
    
    key - the key of the indexed element.
    
    value - the value of the indexed element.
    
    element - the element to remove given the key/value pair.
    
    indexWriters - if not null, the cache of indexWriters to use, this avoids opening/closing index writers at flush time, but locks writing operations over the index.
  - remove
```
public void remove(T element)
```
    Deletes a element from this index
    
    Specified by:
    
    remove in interface OracleIndex<T extends Element>
    
    Parameters:
    
    element - an Element object.
    
    Throws:
    
    IOException
  - removeAll
```
public void removeAll(String key)
```
    Removes all the elements from the index matching the specified key.
    
    Specified by:
    
    removeAll in interface OracleIndex<T extends Element>
    
    Parameters:
    
    key - the key to remove from the index.
  - removeAll
```
public void removeAll(String key,
             OracleIndexWriter[] indexWriters)
