Hi Sebastian! I suppose I won't have problems when upgrading, because I'll do a 2.4 in place upgrade (with no xapian, no indexing) and later a replication to a 3.0 Cyrus with Xapian enabled, where all indexes due to this sync should being generated (it seems logs say that at least...). Is Xapian search slower than "previous way" in some situation?. When talking about a fallback, I meant you know, running Squatter without being in rolling mode and behaving and indexing the way before Xapian appeared... which I suppose it would be used berkeley or similar, but have seen no berkeley support is present in last Cyrus versions so... don't really know which database backend where used... I suppose to some other database type.... Thanks mate!!! --- EGOITZ AURREKOETXEA Departamento de sistemas 944 209 470 Parque Tecnológico.

A few additional comments: With the setting "search_fuzzy_always: 1" all searches use Xapian. Otherwise searches from clients that don't use FUZZY run completely without a search index. There is no fallback mechanism to squatter. You also need to be careful with the conversationsdb. In my experience the DB is not updated when syncing from a 2.4 server to a 3.0 server. That means that you need ro rebuild each user's conversationdb manually using ctl_conversationsdb. ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus Links: ------ [1] http://www.sarenet.es ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
