From 8fdff2748ffbc4ce3d36c75f2bd33182b641e895 Mon Sep 17 00:00:00 2001 From: Eugen Rochko Date: Fri, 16 Aug 2019 01:24:03 +0200 Subject: Add more accurate account search (#11537) * Add more accurate account search When ElasticSearch is available, a more accurate search is implemented: - Using edge n-gram index for acct and display name - Using asciifolding and cjk width normalization on display names - Using Gaussian decay on account activity for additional scoring (recency) - Using followers/friends ratio for additional scoring (spamminess) - Using followers number for additional scoring (size) The exact match precedence only takes effect when the input conforms to the username format and the username part of it is complete, i.e. when the user started typing the domain part. * Support single-letter usernames * Fix tests * Fix not picking up account updates * Add weights and normalization for scores, skip zero terms queries * Use local counts for accounts index, adjust search parameters * Fix mistakes * Using updated_at of accounts is inadequate for remote accounts --- app/models/account.rb | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'app/models/account.rb') diff --git a/app/models/account.rb b/app/models/account.rb index 60c06aaf0..392cc625f 100644 --- a/app/models/account.rb +++ b/app/models/account.rb @@ -127,6 +127,8 @@ class Account < ApplicationRecord delegate :chosen_languages, to: :user, prefix: false, allow_nil: true + update_index('accounts#account', :self) if Chewy.enabled? + def local? domain.nil? end @@ -169,6 +171,10 @@ class Account < ApplicationRecord subscription_expires_at.present? end + def searchable? + !(suspended? || moved?) + end + def possibly_stale? last_webfingered_at.nil? || last_webfingered_at <= 1.day.ago end -- cgit
