Missing in the wilderness

My beloved got out 3 days ago. I've been reading online what to do so I have a box of my things and stuff she loved to lay on outside the door. Her cat box is outside and I also have a trap set. We are out in a very very rural area and I just need some words on encouragement. She is an indoor cat and we just moved out here in February. She has gotten out but I was always there to grab her and take her inside. This time I wasn't there when she got out and it was already dark. We looked that night I knew she wasn't in the house. Nothing. No meows or ringing of her collar. I'm thinking something chased her off. I've gone out every night walking my property, we have 20 acres fenced in. I've told all our neighbors and posted on our community group. No luck. It's now 3 days later and still no sign of her. I'm still looking but what can I do to help her chances of getting back home? I'm completely heartbroken and can't stop crying. I miss my baby. Anything would help hoestly.
