Algolia migration guide improvement

[CaroFG]

On an issue in the devrel repo, a user mentioned the following points:

It would be nice to mention that page in algolia starts from 0 and in meili from 1. Furthermore, attributesToSnippet doesn't exist and there is no mention of forwarding client IP for analytics using X-Forwarded-For for when our client is proxied by our own backend for frontend.

Tasks

• Review Algolia migration guide (https://www.meilisearch.com/docs/learn/update_and_migration/algolia_migration)
  • Add page parameter (present in both, starts from 0 in Algolia, 1 in Meilisearch)
  • Add attributesToSnippet (Algolia only, no direct equivalent)

Not sure about the user's last point. XFF is not specific to Meilisearch nor Algolia.

I think attributesToSnippet corresponds to attributesToCrop
