This is a silly little thing I created to search for words and Wikipedia titles starting or ending with a particular substring.
It's build with Deno.
This will create a database over 2Gb in size and take about 5-10 minutes.
deno run --allow-net --allow-read --allow-write create-db.ts
deno run --allow-read find.ts --starts='hello' | column
For other options:
deno run find.ts --help
