I think it's best to have one small index for each customer, and one large index for company's index.
Merging customers' contents with the main index will cost a lot of resources, slowing down systems, while actually not necessary. If indexing is done by batch job, there'll be a delay between content updated time and index refreshed time. This maybe acceptable for some cases, but usually for users' own content, they want to search it right away. With small individual customer index, indexing won't cost any time for 10~20 small documents. Customers can search their content right after content is updated.
