Hello, I am playing with the text:query property function. The following query searches for var ?a where must meet 2 criteria, one related to predicate pred:cv-name, the other one to predicate pred:cv-synonym.
PREFIX pred: <http://nextprot.org/rdf/pred/> PREFIX afn: <http://jena.hpl.hp.com/ARQ/function#> PREFIX fn: <http://www.w3.org/2005/xpath-functions#> PREFIX text: <http://jena.apache.org/text#> SELECT * where { ?a text:query(pred:cv-name 'ubl' 5) . <== first criterion ?a text:query(pred:cv-synonym 'ubiquitin' 10) . <== second criterion ?a pred:cv-name ?n . ?a pred:cv-synonym ?d . } When I trace the solr index calls, here is what I see: 657968 [qtp1936269821-15] INFO org.apache.solr.core.SolrCore ? [rdf1] webapp=/solr path=/select params={q=cv_name:ubl&wt=javabin&version=2&rows=5} hits=172 status=0 QTime=1 657972 [qtp1936269821-15] INFO org.apache.solr.core.SolrCore ?

[rdf1] webapp=/solr path=/select params={q=cv_synonym:ubiquitin&wt=javabin&version=2&rows=10000} hits=256 status=0 QTime=1 657991 [qtp1936269821-15] INFO org.apache.solr.core.SolrCore ? [rdf1] webapp=/solr path=/select params={q=cv_synonym:ubiquitin&wt=javabin&version=2&rows=10000} hits=256 status=0 QTime=1 It seems that the search related to the second criterion is called once for each solution found for first criterion. Is my interpretation correct ? is there a workaround to compute mutiple text:query and do a single binding to var ?a ? Thanky in advance for your answer, Pierre-André
