what is the filter format for the /addresses/{address_hash}/transactions REST endpoint

[ixje]

The /addresses/{address_hash}/transactions REST endpoint has a filter param according to the swagger docs.

Unfortunately, all it says is to | from. I'm trying to filter the transactions to be within a given block range. I've tried to following without success

• https://xexplorer.neo.org/api/v2/addresses/0x73B9F9215C9f15619aB1955a73be71473471Cc9e/transactions?from_block=917301&to_block=917305
• https://xexplorer.neo.org/api/v2/addresses/0x73B9F9215C9f15619aB1955a73be71473471Cc9e/transactions?filter=917301|917305
• https://xexplorer.neo.org/api/v2/addresses/0x73B9F9215C9f15619aB1955a73be71473471Cc9e/transactions?filter=to|from&from_block=917301&to_block=917305
• https://xexplorer.neo.org/api/v2/addresses/0x73B9F9215C9f15619aB1955a73be71473471Cc9e/transactions?filter=to|from&from=917301&to=917305

I don't know Elixir, but with some searching I believe this endpoint eventually touches on this piece of code

blockscout/apps/explorer/lib/explorer/chain/transaction.ex

Lines 1548 to 1555 in f71924f

	def address_to_transactions_tasks_query(options, _only_mined?, false) do
	from_block = Chain.from_block(options)
	to_block = Chain.to_block(options)
	paging_options = Keyword.get(options, :paging_options, Chain.default_paging_options())
	sorting_options = Keyword.get(options, :sorting, [])
	fetch_transactions_with_custom_sorting(paging_options, from_block, to_block, sorting_options)
	end

which suggests it's possible to filter by passing from_block and to_block as part of options. However that is done is my question.

I tried to ask this question on Discord on #blockscout-api but instantly got a 7 day timeout without any details on what I did wrong (wtf?). From the search results it seems more people are confused on how this works. One question was answered pointing to the RPC API, but that gives a different response. I'm really interested in the REST version.
