Taxonomy filter search

Hi,

I am looking for an advice on how to create a taxonomy filter search. I know there are some youtube tutorials but they are very puzzling to me as a layperson, some even already start with half written codes, which makes it impossible for me to follow. I would love to use a plugin, tried a few already, the ‘Search and filter’ plugin would have been awesome, exactly the easy way I am looking for but unfortunately it is not compatible with my theme or might interefere with other plugins, it just doesn’t work :-/ I need not just one taxonomy filter but I need a search where I can add as many taxonomies as I need on specific pages. Thanks in advance ??
