few moments:

1. Pagination does not work correctly because every time offset parameter is changed a different list of objects is returned. ex offset=0 and offset=10:

2. Did I choose the right filter for search MatchCommonPrefix? It only works from the beginning of the object name and also it only works with FileName, but if you have FilePath attribute you see it like a name:

Yep, unfortunately, there is no sorting in the search request, so the result with offset is pretty random.

I don't think we have any other option here, just the prefix.

This is just a part of #211 in fact. It's OK to have it, but I'd like to see more functionality exposed. The request language is rather rich, we can search by combination of attributes, we can do numeric matches and all of this should be available to users as well. They can add custom attributes right in the panel, so they should be able to make use of them. Specify "color=black" and "color=white", then get all those black cats via search (not name-based).
