I'm brand new here so apologies if this is wrong. I'm using Liftoff & was able to search for & find your post like this:
- From any post tap โฎ menu (top right in Liftoff).
- Select Open in browser (I have Liftoff set to use its in app browser)
- โก menu (top right in Liftoff)
- Tap search
- Select Search = Posts, Instances =All, Sort type = New
- You can leave community as the default All or
- Tap community & type ask
- Wait for the instances to populate, then select lemmy.ml/asklemmy
- ignore that it then reverts the instance back to All
- Creator = All
- Search = type search query here. I used the term "search commumity" then tap Search
- Your post showed up as the top result
Edit: An easier way to do it
- Tap search icon at the bottom of Liftoff
- For me the instance shows as lemmy.world & there's no option to change this
- Type your search query in the search bar eg "search community"
- Your post shows near the top in results
