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>
