Forum:Combine Properties from Main page/Sensor Page in queries

Hi, I'm new to familypedia, could someone please help me with semantic search?

Say, I want to get all descendants of Yaroslav of Kiev, whose given name is Emma.

If I query (brackets omitted):

Ancestors :: ៛;  →; Yaroslav I Vladimirovich of Kiev (c978-1054); ₪

I get a list of descendants' sensor pages. However, to specify given name I have to access Main page, thusif i combine it with:

Given name :: Emma

it won't give any results.

What am I doing wrong?
