Subject What index should I create ?
Date Fri, 20 May 2016 23:38:19 GMT
Hello,
My question is:
What index(es) should I create ? I have 10 columns, where four of  them will
be used as filter (where - equality and inequality) and field for groupby.  
It should be four separate index, as:
                               <constructor-arg value="A"/>
                                                <constructor-arg value="B"/>
                                                <constructor-arg value="C"/>
                                                <constructor-arg value="D"/>
or group index:
                                              <constructor-arg>
                                                  <list>
                                                      <value>A</value>
                                                      <value>B</value>
                                                      <value>C</value>
                                                      <value>D/value>           
                                          
                                                  </list>
                                              </constructor-arg>
