Which feature can be influenced by raising the maximum number of categories per document?

Raising the maximum number of categories per document directly relates to how documents are sorted based on their categorization. When the maximum categorization limit is increased, each document can be associated with more categories, which enhances their classification and sorting capabilities. This influence on the sorting capability allows for a more nuanced organization of documents, facilitating better retrieval and management of information based on the different categories assigned.

While other options may seem plausible in their context, they do not align as closely with the effects of changing the maximum number of categories. Document sharing functionality, visibility in search, and indexing speed are influenced by other factors and not primarily by the number of categories assigned to each document.
