I downloaded the free version a few days ago and I’m considering the license but I’m having some issues that I’m not sure how to resolve. After watching the video on how to use filters I tried to replicate and had issues:

to find a person on their birthday (using filters for the name and birthday), it completed my name (maybe because I’d already identified myself in various pics) but wouldn’t give me “birthday.” It said “no matching filters”
So I how do I resolve that? By creating a tag?
I tried to find photos of my husband and myself (as I’d already linked ourselves to several pictures). That worked better BUT it only identified 12 photos when there are hundreds of us together. Now in People view it says some of his photos are hidden because of free limitations - is that the only reason more photos of him don’t come up in filter search? Or do I need to also be doing something else?
Interestingly when playing with filters it autocompleted a tag for “Sandy Joe wed” – I looked at some of the photos and apparently that phrase exists in some photos in the “keywords” part of the file (when looking in photoshop). So I had some questions about filters/tags
Am I correct in that the filter search will find keywords I might have inserted into a photo separately (as in the previous example)?
But it also seems I have the option of creating tags WITHIN tonfotos to help refine future searches? But what about tags I’ve created via Finder (Mac)? It doesn’t seem like this works, but would be so helpful as I created a ton of tags before finding this software. Or perhaps it’s a limitation of the free version?
I did a search for dog using the filter search and this was the weirdest one of all. I have hundreds of photos of my dogs as well as for work and the search pulled up maybe a dozen. How does this get fixed?
Also, the results pulled up files (but no images) that have NOTHING to do with a dog - examples one was a video of my son (file “hcpiano411” but there is no dog in the video), another is of my husband’s grandfather - file name “FentonAlexmiltary” - again no dog. I attached screenshots of those. Just wondering how to resolve this so the correct items come up.

Thanks so much in advance for clarification and assistance.
