Field Detail

TYPE_NAME

public static final String TYPE_NAME

The name to use for the backend type configuration property so that a Lucene backend is instantiated by Hibernate Search.

Only useful if you have more than one backend technology in the classpath; otherwise the backend type is automatically detected.

Constant Field Values

LUCENE_VERSION

public static final String LUCENE_VERSION

The Lucene version to passed to analyzers when they are created.

This should be set in order to get consistent behavior when Lucene is upgraded.

Expects a Version, or a String accepted by Version.parseLeniently(java.lang.String)

Defaults to LuceneBackendSettings.Defaults.LUCENE_VERSION, which may change when Hibernate Search or Lucene is upgraded, and therefore is really not a good choice. You really should set this property with your own value.

public static final String MULTI_TENANCY_STRATEGY

The multi-tenancy strategy to use.

Expects a MultiTenancyStrategyName value, or a String representation of such value.

Defaults to LuceneBackendSettings.Defaults.MULTI_TENANCY_STRATEGY.
