Hi all After looking the documentation, https://jena.apache.org/documentation/query/spatial-query.html#building-a-spatial-index it is not clear which is the best way to build by program a Dataset that is both textual and spatial.
Both functions take an argument of type Dataset and return an "augmented" Dataset: TextDatasetFactory.create() SpatialDatasetFactory.createLucene() So, in theory, I can create first the textual Dataset, and then from that the spatial Dataset, or the reverse. Is that the way to go? Or is there a way to create in one step a combined Dataset ? Is there a recommended order of creating the "augmented" Datasets, depending on data and usage ? Is there some loss of efficiency compared to using textual or spatial alone ?
