Erroneous 100 Document Limit?

Hello, I'm trying to determine the source of a given issue. We've built a working search interface as part of our application in React Native using ElasticAppSearch and this plugin. However, an issue seems to arise when we try to access documents beyond a certain point, and at a much lower level than the documentation on ElasticAppSearch would suggest.

If we call for the size of a given search request to exceed 100 documents, it always, invariably, returns just up to 100. All further requests beyond that return no results. We know for certain there are more documents than that in our engine, and have even confirmed this by checking against total results. But for whatever reason, that 100 documents limit is resolutely in place.

Do you all have any insight into this problem? Thank you.
