Drupal 8 Commerce Search Api SOLR catalog Domain Access i18n

Hello,

I need help with following tasks with my D8 commerce website:

1. Config Domain Access module (or alternative) to setup 3 different domains where each domain have its own language for languages: English, Swedish, Polish

2. Create Search API product catalog structure with Search Api Solr index (with multilingual support in mind)

3. Create mega-menu based on the product catalog search api structure including "clean urls" for example "womens/sweaters" as link where it would use search api to display all products that are categories as sweaters (using search api" with facets filtring for size, color, material) - multilingual urls most be used including 3 different domain names as stated previously

4. Generating clean urls for products for each domain name with product titles as part of title in respective language, If you have read it all please write the following just testing at the top of the proposal

5. Generating different XML sitemap for google for each domain access website to make it in SEO FRIENDLY WAY so all domains could get indexed and none would be penalized for duplicated content

6. Generating google analytics code for the multilanguage setup.
