[Dovecot] search gives variable/different results

[W. de Hoog]

Hi,

When I perform a search using doveadm every time it returns different 
results. For example:

$ doveadm search mailbox shared/\* TO stromvers
938ff10527d6be515f5900007b46f991 6
938ff10527d6be515f5900007b46f991 7
938ff10527d6be515f5900007b46f991 8

$ doveadm search mailbox shared/\* TO stromvers
6a8ff10527d6be515f5900007b46f991 1
