Relay Search does its queries using Onionoo, which is a JSON service.
Depending on your needs, you may be able to just query Onionoo directly
and convert the result to TSV using jq (https://stedolan.github.io/jq/).

Here's an approximation of the Relay Search index output:
$ wget -O - 'https://onionoo.torproject.org/details?country=de' | jq -r '(.relays,.bridges)[]|[.nickname,.observed_bandwidth,.last_restarted,.country,.or_addresses[0],(.flags|join(","))]|@tsv' > de.tsv

There are many other fields available:
