If bi-encoder and cross-encoder have a limit of 300-400 words, what happens if we give an article with more than the limit, will it just take the initial 400 words and ignore everything after that? , Also even if we split an article into 5 to 6 parts and encode them individually how we are going to maintain the context will it not split the context as well considering 1 article is a solution for 1 issue?
