| A multi-index is a CARv2 index format that allows multiple CARv2 indexes to be grouped together in a single index. |

I may be missing something and/or this might grow on me, but there's a pedant inside me saying that when we talk about multi* things in the IPFS ecosystem (ie, multihash, multiaddress) we're usually talking about a string of bytes that may be one of a number of different formats, and so when I glanced at this the first thing I thought was "oh this is about a thing that lets you disambiguate different strings of bytes that represent encoded indices" rather than "this is a thing that concatenates different indices together."
Not remotely a blocker, but might be worth clarifying or trying to find a different name - at the very least I just want to confirm that this isn't a multi* thing in the sense of multihashes or multiaddresses, is that right?

Bonus points if you can work a Voltron or Power Rangers reference into the name since this is sort of like a Megazord for indices?

Yes that is correct - I'm open to a better name suggestion 🙂
CombinedIndex, AggregateIndex...? ...not sure. Want to express that it's not just a joining, since it also carries information about what CAR each index pertains to.

This is a good feedback, I also thought about the naming creating some confusion. Could DagIndex or would we want to use this out of the context of representing a Dag? I think that naming could work well given it can be an index for either a root CID having all its blocks, as well as sub-dags that could be optimized.

@travis I could get behind ZordIndex...

CombinedIndex- join or merge to form a single unit or substanceCompositeIndex- made up of several parts or elementsCompoundIndex- a thing that is composed of two or more separate elements
Would be good to get a name sorted - I'd like to merge this as we're using it in production for rollup indexes in freeway.

ShardedDAGIndex- for when a DAG is sharded amongst multiple CARs
