how to create a segment "return visits from organic search" in sitecatalyst 15
Hi, I want to create a new segment on "return visits from organic search" in SC 15. I know how to create a segment on return visits and I saw "organic search" in "pre-configured". But I don't know how to create a new segment that combines 2 conditions. To be specific, I don't know how to create organic search segment. In the "pre-configured", i saw it was setup as "paid search equals 0". However, i could not find "paid search" when choosing from the drop-down menu "where"; what I could see relevant are only "search engine-organic" or 'search keywords-organic".
Can anyone tells me how to create organic search segment? So i can combine two conditions to create "return visits from organic search". Thanks!
