 Doing a deep composition will also allow you to use the `child_branch_factor` parameter for `/index query`, increasing this past 1 will take a much longer time to query and will be much more expensive for large documents, so be wary.
 
-**When doing Deep Compositions, it's highly reccomended to keep the document size small, or only do deep compositions on single documents.** This is because a deep composition reorganizes the simple index into a tree structure and uses GPT3 to summarize different nodes of the tree, which will lead to high costs. For example, a deep composition of a 300 page lab manual and the contents of my personal website at https://kaveenk.com cost me $2 USD roughly.
