Advanced index usage

I don't understand why I can't do any of this with a index. I didn't see in the docs a explicit explanation that you couldn't do something like this using the available .eq,gt,gte,lt,lte so i tried a few things.
assume ['by_index1_index2_index3']
(q) => q
  .gt('index1', null
  .eq('index2', index2)
  .gt('index3', '2')
  .lt('index3', '4')

(q) => q // just ignore index1 enitrely
  .eq('index2', index2)
  .gt('index3', '2')
  .lt('index3', '4')

(q) => q 
  .eq('index1', index1)
// just ignore index2 but use to sort. 
  .gt('index3', '2')
  .lt('index3', '4')

(q) => q 
  .eq('index1', index1)
  .gt('index2, '1'
  .gt('index3', '2')
  .lt('index3', '4')

(q) => q 
  .eq('index1', arrayOfOptions)
  .eq('index2, '1'
  .gt('index3', '2')
  .lt('index3', '4')
assume ['by_index1_index2_index3']
(q) => q
  .gt('index1', null
  .eq('index2', index2)
  .gt('index3', '2')
  .lt('index3', '4')

(q) => q // just ignore index1 enitrely
  .eq('index2', index2)
  .gt('index3', '2')
  .lt('index3', '4')

(q) => q 
  .eq('index1', index1)
// just ignore index2 but use to sort. 
  .gt('index3', '2')
  .lt('index3', '4')

(q) => q 
  .eq('index1', index1)
  .gt('index2, '1'
  .gt('index3', '2')
  .lt('index3', '4')

(q) => q 
  .eq('index1', arrayOfOptions)
  .eq('index2, '1'
  .gt('index3', '2')
  .lt('index3', '4')

neq would solve some of this.. but how can just getting all of a index break things too.
Is any of it going to be supported or just via that eventual sql style "adapter"

In one real world example i have a events table with ['lastStatus', 'userid', 'eventType'] where i also have have a index [ 'userid', 'eventType'] when i want all statuses from that user. A gte null on lastStatus index would keep me from duplicating effort.

Probably the most annoying one is to get the last 10 results since a certain time while getting a range of eventTypes for a user ['recordedAt', 'userid', 'eventType']

I fail to see how anyone could ever use more than a few indexes if all but the last one requires .eq usage. I certainly cant imagine complex use cases, I'd love to see some real world work arounds. Or how others here are creating separate tables etc to get more specific.

Hi @everyone with everything going on today I forgot to post on discord about our EU launch! We have a region in Dublin now! You can start using it immediately, even for folks on the free plan. https://news.convex.dev/we-finally-got-our-eu-visa/ Stay tuned for more regions but also stay tuned for more infra improvements where we improve latency for teams no matter where their servers are located. Just at the tip of the iceberg re all the optimizations we have lined up.
