I'm using GraphDB-SE 6.4.4 and deployed graphdb-workbench using the startup.sh script. Our repository has 134 million statements and we want to use full text search instead of regex filter for faster query result. I tried the Proprietary Full-Text Search described here: https://confluence.ontotext.com/display/GraphDB64/GraphDB-SE+Full-text+Search#GraphDB-SEFull-textSearch-NodeSearchProprietaryFullTextSearch

and tried the query like this:

PREFIX fts: <http://www.ontotext.com/owlim/fts#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
    ?X rdfs:label ?label .
    <searchingString:> fts:prefixMatchIgnoreCase ?label. }

but it returns no result. I tried several different searching strings, no result. The range of rdfs:label is string and they are explicitly typed as ^^xsd:string, so a sample object of rdfs:label would be "some string"^^xsd:string . I also tried without ^^xsd:string in the object, but it makes no difference. No result.

Below is the parameters I have set in the startup.sh script and they are shown in the system information page:


my repository setting is listed in the picture: alt text

Do you know why full text search does not work for me?

the proprietary Full Text Search has been deprecated in latest versions of GraphDB, you can try the FTS using Lucene: link text

Sorry for not mentioning that in our documentation
