Thanks Andy... However I don't fully understand the philosophy. 1) From the examples it seems I have to create special queries to use the indexes? Am I right?
2) I guess the indexes can be also stored in a kind of TDB and not only memory. Then do I have to always open the "special" dataset explicitly? isn't any way that the main dataset TDB is directly linked to the Lucece created one. Problably is that I'm really new to the indexes stuff and this is my fault (I have to read more ;)) REgards On 2017-09-22 20:52, Andy Seaborne wrote: > Documentation: > > http://jena.apache.org/documentation/query/text-query.html#configuration-by-code > > > Example: > > https://github.com/apache/jena/blob/master/jena-text/src/main/java/examples/JenaTextExample1.java > > > Andy > > On 22/09/17 10:42, George News wrote: >> Hi, >> >> could you please provide an example of directly working with indexes >> from Jena API? >> >> I have a TDB directly created using: >> private static final Dataset dataset = >> TDBFactory.createDataset(tripleStorePath); >> >> Now that I have pretty much of the functionality to interact with it, >> I want to create indexes.
