By default, Algolia sets all attributes as searchable, but you are able to define a specific list of “searchable attributes”.
If you do not think the
body should be searchable at any point, then at the outset define your list of
searchableAttributes and exclude
body from that list. You can find the searchable attribute documentation here and here.
If you do think that
body should be searchable sometimes, but just not in this instance, you can use
restrictSearchableAttributes attributes and exclude
body from the list.
