## org.modeshape.search.lucene
Class LuceneSearchWorkspace

    java.lang.Object
      org.modeshape.search.lucene.LuceneSearchWorkspace

All Implemented Interfaces:
  SearchEngineWorkspace

    @Immutable
    public class LuceneSearchWorkspace

extends Object
implements SearchEngineWorkspace

The `SearchEngineWorkspace` implementation for the `LuceneSearchEngine`.

Field Summary
`protected org.apache.lucene.analysis.Analyzer` | `analyzer`
`protected static int` | `CHANGES_BEFORE_OPTIMIZATION` Apparently Lucene indexes must always be optimized prior to committing, so this value is set to '1'.
`protected org.apache.lucene.store.Directory` | `contentDirectory`
`protected static String` | `FULL_TEXT_PREFIX` Given the name of a property field of the form "<namespace>:<local>" (where <namespace> can be zero-length), this provider also stores the value(s) for free-text searching in a field named ":ft:<namespace>:<local>".
`static String` | `INDEX_NAME`
`protected IndexRules.Factory` | `rulesFactory`

Constructor Summary
`protected` | `LuceneSearchWorkspace(String workspaceName, LuceneConfiguration configuration, IndexRules.Factory rulesFactory, org.apache.lucene.analysis.Analyzer analyzer)`

Method Summary
`void` | `destroy(ExecutionContext context)` Destroy the indexes for the workspace with the supplied name.
`IndexRules` | `getRules()`
`org.apache.lucene.util.Version` | `getVersion()` Get the version information for Lucene.
`String` | `getWorkspaceName()` Get the name of the workspace.
`protected boolean` | `isOptimizationRequired(int changesInSession)` Give the number of changes that have been made in a session, determine whether optimization is required on the workspace indexes.

Field Detail

### CHANGES_BEFORE_OPTIMIZATION

    protected static final int CHANGES_BEFORE_OPTIMIZATION

  Apparently Lucene indexes must always be optimized prior to committing, so this value is set to '1'.

    Constant Field Values

### INDEX_NAME

    public static final String INDEX_NAME

See Also:
  Constant Field Values

### FULL_TEXT_PREFIX

    protected static final String FULL_TEXT_PREFIX

  Given the name of a property field of the form "<namespace>:<local>" (where <namespace> can be zero-length), this provider also stores the value(s) for free-text searching in a field named ":ft:<namespace>:<local>". Thus, even if the namespace is zero-length, the free-text search field will be named ":ft::<local>" and will not clash with any other property name.

    Constant Field Values

### rulesFactory

    protected final IndexRules.Factory rulesFactory

### contentDirectory

    protected final org.apache.lucene.store.Directory contentDirectory

### analyzer

    protected final org.apache.lucene.analysis.Analyzer analyzer

Constructor Detail

### LuceneSearchWorkspace

    protected LuceneSearchWorkspace(String workspaceName,
                                    LuceneConfiguration configuration,
                                    IndexRules.Factory rulesFactory,
                                    org.apache.lucene.analysis.Analyzer analyzer)

Method Detail

### getWorkspaceName

    public String getWorkspaceName()

  Get the name of the workspace.

  Specified by:
    `getWorkspaceName` in interface `SearchEngineWorkspace`
  Returns:
    the workspace name; never null
  See Also:
    `SearchEngineWorkspace.getWorkspaceName()`

### destroy

    public void destroy(ExecutionContext context)

  Destroy the indexes for the workspace with the supplied name.

  Specified by:
    `destroy` in interface `SearchEngineWorkspace`
  Parameters:
    `context` - the execution context in which the destruction should be performed; may not be null
  See Also:
    `SearchEngineWorkspace.destroy(org.modeshape.graph.ExecutionContext)`

### getRules

    public IndexRules getRules()

  Returns:
    rules

### isOptimizationRequired

    protected boolean isOptimizationRequired(int changesInSession)

  Give the number of changes that have been made in a session, determine whether optimization is required on the workspace indexes.

  Parameters:
    `changesInSession` - the number of changes made within a session using this workspace
  Returns:
    true if the workspace indexes should be optimized, or false otherwise

### getVersion

    public org.apache.lucene.util.Version getVersion()

  Get the version information for Lucene.

  Returns:
    the version information; never null
