For non $or queries, the query optimizer attempts to speculatively evaluate a query using multiple indexes in parallel, until 101 matches are found with a single index.

For $or queries, each $or clause can potentially speculatively evaluate multiple indexes. However, after 101 total matches are found speculative evaluation is stopped and an index is chosen arbitrarily for each $or clause.

This ticket represents allowing speculative index evaluation in $or clauses even after the first 101 matches are found.
