Andy Seaborne commented on JENA-470:


The code was correctly finding the better algebra but failing to determine it 
could return the mixed expression.

[jira] [Updated] (JENA-470) Optimizer misses optimization when there are multiple filter possibilities.

[Andy Seaborne (JIRA)]

 [ 
https://issues.apache.org/jira/browse/JENA-470?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Andy Seaborne updated JENA-470:
---

Description: 
{noformat}
public static void main(String[] args) {

String qs= StrUtils.strjoinNL("PREFIX : ",
  "SELECT * {",
  "  ?s  ?o . ?s  ?v . ",
  "  FILTER (?o =  || ?o =  )",
  //"  FILTER (?o =  )",
  "  FILTER (?v > 5)",
  "} ");

Query query = QueryFactory.create(qs) ;
//Query query = QueryFactory.read("Q.rq") ;

System.out.println(query) ;
Op op1 = Algebra.compile(query) ;
Op op2 = Algebra.optimize(op1) ;
System.out.println(op1) ;
System.out.println(op2) ;
}
{noformat}


This query does not have the disjunction/equality optimization applied.

The simple equality FILTER case does get it applied.

The (?v>5) is causing the block.
