The Lucene full-text index provided by the triplestore is used to perform full-text searches in Knora. The exact behavior can be different depending on the triplestore.
Lucene Query Parser Syntax
Full-text searches in Knora are based on Lucene. Therefore, full-text searches support the Lucene Query Parser Syntax.
A full-text search consists of a single word in the simplest case, but could also be composed of several words combined with Boolean operators. By default, Lucene combines two or more terms separated by space with a logical OR.
For examples, see Lucene Query Parser Syntax.
