Minimal working Fuseki TDB with with full text search.

##Fuseki minimal full text search

See the Jena text query docs for full explanation. This is a minimal sample config for setting up full text search for an existing Fuseki TDB.

###indexing Indexing an existing loaded TB with:

java -cp fuseki-server.jar jena.textindexer --desc=./fuseki-fulltext-config.ttl

###sample query

## Example of a TDB dataset and text index
## Initialize TDB
[] ja:loadClass "com.hp.hpl.jena.tdb.TDB" .
tdb:DatasetTDB  rdfs:subClassOf  ja:RDFDataset .
tdb:GraphTDB    rdfs:subClassOf  ja:Model .

## Initialize text query
[] ja:loadClass       "org.apache.jena.query.text.TextQuery" .
# A TextDataset is a regular dataset with a text index.
text:TextDataset      rdfs:subClassOf   ja:RDFDataset .
# Lucene index
text:TextIndexLucene  rdfs:subClassOf   text:TextIndex .
# Solr index
text:TextIndexSolr    rdfs:subClassOf   text:TextIndex .

## ---------------------------------------------------------------
## This URI must be fixed - it's used to assemble the text dataset.

Can you provide me a sample video demo to do text indexing in fuseki using WAR file in tomcat for sample data , When we are trying to load the data it shows zero triples and SPARQL response is not as expected.

Hello I'm having the same problem. have you solve it?
