How to tell Google and Yandex about Ajax pages?

Question

Google

There is a directory with a large number of pages (each page has its own address , example: http://site/name/05458 ), pages are loaded using ajax when scrolling the page to the bottom or when filling out a search form.
How to tell Google and Yandex search engines about the presence of these pages?
Write in robots.txt or sitemap.xml?
And what to write?

Answer 1

And what does robots.txt have to do with it? Of course, this should be written in sitemap.xml. Just feed your sitemap to the PS and wait for those pages to be indexed. My flash site was fully indexed thanks to the sitemap. If you have a site on the engine, then for sure there is a sitemap generator. If not, then write a generator, do not manually prescribe 100500+ pages
