Re: [dotNetRDF-Support] R: search string "contains"

[Rob V. <rv...@vd...>]

Hi Pier

The files are not supposed to be readable by humans ­ they are Lucene
indexes understood by Lucene! [1]

The indexer.Index(this.GetTestData()) was a typo, I have corrected it now.
You can call indexer.Index() with any Triple, IGraph,  or ISparqlDataset
instance.

In the example note the line at the start:

//This example assumes we've already created our index in a folder called
example

The example is assuming you've already created an index and populated it, if
the index has not been created or populated then provider.Match() is never
going to be able to return any answers
