From 0f48341ed67624f8bf113737eac0ba5b989133b3 Mon Sep 17 00:00:00 2001 From: Lukas Fleischer Date: Fri, 22 May 2015 13:29:59 +0200 Subject: Do not allow more than 20 terms in search queries Specifying a huge number of search terms currently results in complex SQL queries. In practice, queries with more than 20 terms are rarely needed. Ignore everything apart from the first 20 keywords to prevent from potential abuse.
