Jena text Search

[Kamalraj Jairam]

Hello All,

I have number of data properties in TDB dataset with ranging Uris

I want to create a lucene index on these data properties so that any partial 
text search is fast.

I read the document on Jena Website, but i have some questions on what needs to 
be done

This is what the text says

// Example of building a text dataset with code.

    // Example is in-memory.
    // Base dataset
    Dataset ds1 = DatasetFactory.createMem() ;

    EntityDefinition entDef = new EntityDefinition("uri", "text", RDFS.label) ;

    // Lucene, in memory.
    Directory dir =  new RAMDirectory();

    // Join together into a dataset
    Dataset ds = TextDatasetFactory.createLucene(ds1, dir, entDef) ;

What should go in the Uri - > is it the base Uri?

What should go in the “Text” ? can this be left blank?

Thanks
