Interface LuceneIndex

public interface LuceneIndex

LuceneIndex represents the Lucene index created over the data stored in Apache Geode regions. The Lucene indexes are maintained automatically by Apache Geode whenever the entries are updated in the associated regions. Lucene Indexes are created using LuceneService.createIndexFactory() by specifying the Lucene index name, the region associated with the Lucene index and the fields on which the Lucene index is to be created.

Every Lucene index is uniquely identified by the index name and the name of the region associated with it. To obtain the LuceneIndex created over a region use LuceneService.getIndex(String, String)

LuceneIndexes are created using gfsh, xml, or the Java API using LuceneService LuceneService.createIndexFactory(). More information about LuceneIndex can be found at LuceneService
