Re: [Virtuoso-users] New version with very slow free text search

[Patrick van Kleef]

Hi Bruno.

I upgraded to Version 06.01.3.3127-pthreads linux and some queries that ran on 4 seconds or less are now taking 45 seconds.

Also, the commercial version Version 06.02.3129-pthreads have similar problems.

One query that got a lot worse was:

sparql  define input:inference <http://semantica.globo.com/ruleset>
           select distinct ?s ?label
               {

                   {graph <http://semantica.globo.com/esportes/>
                   {

?s a <http://semantica.globo.com/esportes/ Jogo> ; ?p ?o .

                       ?o bif:contains "'22/05/2011*'" .
                       ?s rdfs:label ?label .
                   } }
                   UNION
                   { graph <http://semantica.globo.com/>  {

?s a <http://semantica.globo.com/base/ Evento> ; ?p ?o .

                       ?o bif:contains "'22/05/2011*'" .
                       ?s rdfs:label ?label .
                   } }
                   UNION
                   {  graph <http://semantica.globo.com/esportes/>  {

?s a <http://semantica.globo.com/esportes/ Prova> ; ?p ?o .

                       ?o bif:contains "'22/05/2011*'" .
                       ?s rdfs:label ?label .
                                            }   }
                   UNION
                  { graph <http://semantica.globo.com/esportes/>   {

?s a <http://semantica.globo.com/esportes/Edicao_de_campeonato > ; ?p ?o .

                       ?o bif:contains "'22/05/2011*'" .
                       ?s rdfs:label ?label .
                   }  }

               }
               ORDER BY (?label)
               LIMIT 10;

Is anyone experiencing the same problems ?

We are already in contact with Roosevelt on this query.

Please check with him for solution.
