Legal structure for the search phase (European search)

I would love an opportunity to speak with traditional searchers (and/or investment professionals) about the legal structure used for the search phase in Europe and the rationale behind it. For context, I am fundraising for a traditional search fund based in Poland. To the best of my knowledge, prior searchers in the Polish market applied a Delaware structure. However, based on investor feedback, I am considering establishing a local Polish structure going forward. I hear that a local structure is a prevalent one in most European countries and I would love to learn more.
