408 Database timed out. Try adjusting your queries or adding an index.

Have a large collection and am getting this when trying access it via the console or the make queries, tried adding a index via api and modifying my search parameters but it had no effect

my collection has 4 million+ documents if that alone is causing a issue let me know the best way to resolve this, i can start over and separate my data into different collections or database if needed, whichever is more effective

but I do have to separate the data I would still like to know whats causing this issue so i know how to best prevent it in the future
