Support multi-search where some indexes may not have an embedder #2055
Description
Description
Using multi-search is very nice, especially when paired with react-instant search. However, when a single index doesn't have the same embedder configured, the whole thing breaks.
It would be nice (if even possible) to set a flag indicating indexes without an embedder simply falls back to regular search mechanics.
bonus if one can configure the desired embedder per index (although right now we use the same across all so of less importance)
