Description g.danti 2020-11-30 16:23:05 UTC
Description of problem:
RedHat 8.x ships with cyrus-imapd version 3.0.x which has broken squat full-text search as per this github issue: https://github.com/cyrusimap/cyrus-imapd/issues/2598

The official recommendation is to use xapian to replace squat seach; however, the shipping packages is compiled *without* xapian support. Please repackage it enabling xapian search (--eneble-xapian).

Alternatively, please help upstream to fix squat indexes.

Version-Release number of selected component (if applicable):
3.0.7

How reproducible:
a) install cyrus-imapd, enable squat indexing, run squatter and try a full-text search: it will not be served by reading the squat file, rather a linear search will be issued (ie: no indexes are used).
b) disable squat and enable xapian, then run squatter - nothing will be really done (no index will be created) and searches remain slow.

Steps to Reproduce:
As above

Actual results:
Full text search are not working, resulting in linear search between all messages

Expected results:
An index (either squat or xapian) should be used to accelerate full text search

Comment 3 g.danti 2020-12-01 07:37:57 UTC
Hi Pavel, this is not a support request.

The shipping cyrus-imapd packages has broken full text search because:
a) the squat index is not used;
b) xapian in not compiled it.

This means that anyone using cyrus on RHEL is going to suffer from the slow search speed, irrespective of its configuration.
Regards.
