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

[Buongiorno, P. <pbu...@es...>]

Hi Rob!
Thank you for answering,
I already tried to do what you suggest, but it doesn't work.
According the guide http://www.dotnetrdf.org/content.asp?pageID=Full%20Text%20Querying%20with%20SPARQL
I created the calls for indexing the rdf, but the files resulting are unreadable. It generates 2 files:
segments_1
segments.gen
both of them contain a line with unreadable simbols, and the next class FullTextSearchExample doesn't return any result after the provider.Match
Can you help me?
I want also ask about the call to method: indexer.Index(this.GetTestData()); present in the FullTextIndexingExample, it returns me an errore saying that is impossible to call this in a static method.
I don't know how to proceed, please suggest me what to do!
Thanks you all!

Hi Pier

Have you taken a look at the documentation on Full Text Querying with SPARQL [1]?

This is a SPARQL extension supported by dotNetRDF that uses Lucene to provide full text search capabilities over RDF.  You can plug it in so SPARQL queries can use full text style searches or you can use the underlying API provided in the dotNetRDF.Query.FullText library directly to index and search RDF graphs.

Hope this helps,

Rob Vesse

Subject: [dotNetRDF-Support] search string "contains"

Hi,
I would kmow if there is a way to search an element in a owl/rdf file giving a substring, or a "Like" text
For example if I enter the string "Godfather", I can have the result "The Godfather" (that is the correct string present in the owl/rdf file)
Thanks you all
Pier
