Frösön

Frösön (Swedish: [frøːsøːn], Jamtlandic: [fɾøːsœʏːa]; "Frey's island") is the largest island in the lake Storsjön, located west of the city Östersund in Jämtland, Sweden. During most of recorded history the island was the regional centre of Jämtland.

Frösön is the location of the "Frösö Runestone", the northernmost raised runestone in the world, dating from 1030-1050 AD.[1] Frösön was a separate köping until 1974 but was merged with Östersund at that time.

The island is named after the Norse god Freyr.

The Swedish composer Wilhelm Peterson-Berger had a summer house (and from 1930 a permanent home) on the island.[2] In 1896 Peterson-Berger composed a set of piano pieces entitled Frösöblomster (Flowers of Frösön), and his opera Arnljot from 1910 is partly based on the runic inscriptions on Frösö Runestone.

gollark: Basically, if I want to run a search it just goes `SELECT * FROM page_tokens WHERE token = 'one token in search query'` or something like that, and it now has a list of pages with the right token, and SQLite can execute this query relatively fast.
gollark: I mean, as far as I can tell there isn't really a faster *and* more storage-efficient way to do search than the inverted-index page_tokens thing.
gollark: ```sqlCREATE TABLE crawl_queue ( id INTEGER PRIMARY KEY, url TEXT NOT NULL UNIQUE, lockTime INTEGER, added INTEGER NOT NULL, referrer TEXT);CREATE TABLE pages ( id INTEGER PRIMARY KEY, url TEXT NOT NULL UNIQUE, rawContent BLOB NOT NULL, rawFormat TEXT NOT NULL, textContent TEXT NOT NULL, updated INTEGER NOT NULL);CREATE TABLE page_tokens ( id INTEGER PRIMARY KEY, page INTEGER NOT NULL REFERENCES pages(id), token TEXT NOT NULL, weight REAL NOT NULL);CREATE TABLE links ( id INTEGER PRIMARY KEY, toURL TEXT NOT NULL, fromURL TEXT NOT NULL, lastSeen INTEGER NOT NULL, UNIQUE (toURL, fromURL))```Here is the database.
gollark: To be fair, the text content field isn't that necessary, as for search it uses the page_tokens table anyway and it can be rebuilt from the HTML if I need it.
gollark: The frequency of every word *must* be stored for quick (O(log n) time or something) search, the raw HTML or at least might be needed if I come up with a better way to weight frequency or something, the links are useful for (future) better search ranking algorithms.
