Hi, I am trying to get faster search results on our webmail client(Roundcube). Besides using Lucene for FTS are there other options? Would having all mails indexed give fast results? Currently the time it takes to search 25,000mails is 4mins. If indexed how much faster are we looking at? Really appreciate if someone could advise about this. Thanks Kevin

With a current version of Dovecot a search is pretty fast _without_ using external indexes. I have a view defined (virtual plugin) with around 22.000 messages in it, and searching the full view only takes 2.5 seconds:

I have a view defined (virtual plugin) with around 22.000 messages in it
interesting. I assume you drop multiple mailing lists together in a mailbox and separate them using the virtual plugin, right? could publish how you configured dovecot virtual plugin? I never had success on using the plugin in a useful way :-/
Thanks Andreas

The namespace "Virtual" will look for its configuration in the user's home directory:
namespace { location = virtual:~/mdbox/virtual prefix = Virtual/ separator = / }
Inside the ~/mdbox/virtual directory the actual query is defined in directory 'Flagged' (that will show up in the MUA as sub-dir). The actual search/query is defined in file 'dovecot-virtual' which will create the "magic":
$ cat virtual/Flagged/dovecot-virtual * Public/* flagged
Another example, the one I used in the original reply, is 'gluing' together archives as a single view:
$ cat virtual/Postfix-Users/dovecot-virtual Public/Archive/Mailing-Lists/Postfix-Users/* Public/Mailing-Lists/Postfix-Users all
HTH

once setup correctly it works like expected :-)

Good!
how do you separate older postings into the Archive? something like "doveadm search + move ?
Yes basically with move. I'd like to have them archived by year e.g. Public/Archive/Mailing-Lists/Dovecot/2014. Being lazy when it comes to repetitive tasks, I wrote a little script for it. It gives a good idea how to do it (hopefully). Please note that this only has minimal error handling as I'm setting most parameters in the script rather than the shell - butterfingers... No bashism comments please :)
$ cat dovearchive.sh #!/bin/bash # Archive old posts before certain date to 'Public/Archive/Mailbox/Year' # Set basic parameters accordingly: # archive=2011, before_date=$year-mm-dd # source_mailbox_base=Public/Newsletters # dest_mailbox_base=Public/Archive/Newsletters # Actual Mailbox is read from command line set -e archive=2014 let year=$archive+1 before_date=$year-01-01 mailbox_owner=tlx@leuxner.net source_mailbox_base='Public/Mailing-Lists' dest_mailbox_base='Public/Archive/Mailing-Lists' #acl_admin_group=owner acl_admin_group='group=PublicMailboxAdmins' acl_unlock_seq="$acl_admin_group delete expunge insert lookup post read write write-seen write-deleted" acl_lock_seq="$acl_admin_group insert lookup post read write write-seen" acl_lock_archive="$acl_admin_group insert lookup read write write-seen" debug_acl_mailbox_path='path: '

This all sounds interesting. Is there anything i can read to understand what the purpose of Virtual is and why this would help? It sounds like you are using a shared space for mailing lists (which I can see would be useful if you had many people subscribing to the same lists). If so, doesn’t each user lose their indications of what messages are read or replied to?

It's a bit hard to wrap your head around it in the beginning, but once you understand what it can do, I'm sure you'll find a use case. Think of it as special view for all messages in Dovecot. You define which set of messages you want to display as a mailbox/folder. This view (or multiple views) is being updated dynamically going forward.
For instance you can set up a certain filter/selection like you can with a modern MUA. The difference however is: your Virtual view(s) will be available regardless which client you are using, whether they have integrated filters capabilities - or not.
Hi Thomas, That's very interesting. Below is my search result. Any idea why is my result so slow:- Appreciate if you could advise. Thanks Kevin

Currently the time it takes to search 25,000mails is 4mins. If indexed how much faster are we looking at?
With a current version of Dovecot a search is pretty fast _without_ using external indexes. I have a view defined (virtual plugin) with around 22.000 messages in it, and searching the full view only takes 2.5 seconds:

Also tried to reload the config but still getting slow search. Just tried to reindex the box by running
dovecot index -u user@email.net inbox
I am still getting searches close to 2:45 minutes. It seems strange.
A smaller inbox took less time:-

Really hard to say what commit probably fixed that already. Dovecot uses a very dynamic development model. There are old versions like 2.0.9 which people still try to get help with since they are in some dusted distro repository, but known to have partially broken features... Looking at the CVS of Dovecot there are so many changes it's really hard to say there was an issue or not.
http://hg.dovecot.org/dovecot-2.2/shortlog
One changelog (2.2.11) however indicates the search was not working as it should:
- IMAP: SEARCH/SORT PARTIAL was handled completely wrong in v2.2.11+
You may want to look at the official Enterprise repository which does support Ubuntu. This one does have the current stable releases in it and is not undergoing so many changes compared to the CVS auto-compiles also offered:
http://shop.dovecot.fi/home/8-dovecot-ee-repository-access.html
Give that one a try with vanilla search...

This is in the repo. My version just has *all* the latest changes applied which sometime can be untested.
Dear Thomas, Could you advise(or provide a link to) for a safe way to upgrade the Dovecot version. I am a little worried about testing and making trial-and-error approach as it could be risky. Appreciate if you could help with this. I have been trying to address this "slow search" issue for a while with very limited success(I was trying to implement FTS also), so I will appreciate if you could support. Apologies for my noobness. Thank You Kevin
Do you have much ideas on how to upgrade dovecot. I am little worried about upgrading dovecot as there could be risks to data. I am trying to upgrade from 2.2.9 to 2.2.15 or Dovecot-EE.

From what I have read is that I cannot automatically install dovecot, I would need to add the repos to my repo list and then use pining to install
Dear Thomas, the latest version. Kindly advise if I am on correct track?

Hi guys, Please correct me if I am adding repos to dovecot correctly. I hope I am doing it correctly
Step 1. Add the following repos to the following file /etc/apt/sources.list.
deb http://xi.rename-it.nl/debian/pool/stable-auto/dovecot-2.2/ trusty universe deb-src http://xi.rename-it.nl/debian/pool/stable-auto/dovecot-2.2/ trusty universe
Step 2. apt-get update
Step 3. apt-get build-dep dovecot-2.2
Step 4. apt-get -b source -t trusty dovecot-2.2
I hope the process listed above is correct and that if I execute it I wont end up in a mess. Please comment. Thanks Kevin

Do you think I should try 2.2.15? Or stick to EE?
This is in the repo. My version just has *all* the latest changes applied which sometime can be untested.

Hi Thomas, That's very interesting. Below is my search result. Any idea why is my result so slow:- Appreciate if you could advise.
It depends on a couple of facts. Full text searches must go through a number of bottle necks, depending on your installation, namely:
a) type of disk drive(s), b) way of installation of those drives, c) the underlying file system itself, d) the storage format being chosen to save the mails, e) how many users you've got on your system, f) memory of your system, g) CPU power of your system and h) how busy your system is.
If you got for example a lonely box with let's sax four gigs of RAM and you are using it by yourself only, chances are high enough that even with a big enough up time most of your mails are in the file system cache of your OS. Meaning a full text search would happen mostly in RAM and therefor of course would be blazingly fast.
If you take the same machine and let it serve let's say about 2000 mailboxes, this would be a very different kind of matter. Your file system cache would be flushed frequently and full text searches without index would be way slower, because now those search actually mean I/O operations for Dovecot on your type of storage.
If you really want consistent, fast full text search speeds on a busy box, incremental full text indexing is the only way to go.
If you are the only user of a big box chances are high you get similar results without.
Dear Marc, Noted. This is starting to make a lot of sense. Of course, more computing power, hence more performance. Also filesystems and such all have and effect on the outcome. I might experiment with adding more computing power and seeing the result. My mailbox does not have many users so I might try that. Currently running a 2gb RAM with 2core processors.

Currently the time it takes to search 25,000mails is 4mins. If indexed how much faster are we looking at?
With a current version of Dovecot a search is pretty fast _without_ using external indexes. I have a view defined (virtual plugin) with around 22.000 messages in it, and searching the full view only takes 2.5 seconds:
hmmm, could you please tell me more about your setup? What storage format do you use? Maildir or? What is the cumulative size of your messages?

Dear Peter,
My inbox is MDA_external Storage: 17GB of 24GB
Subject / From / To is fast but FTS(Full Text Search) for body is horrible. I suppose this is where we need Apache Solr.
Do you think my mail storage format is bad? Do I need to change for better performance? Please advise Kevin

Dear Peter,
My inbox is MDA_external Storage: 17GB of 24GB
Subject / From / To is fast but FTS(Full Text Search) for body is horrible. I suppose this is where we need Apache Solr.
Do you think my mail storage format is bad? Do I need to change for better performance? Please advise Kevin

Currently the time it takes to search 25,000mails is 4mins. If indexed how much faster are we looking at?
With a current version of Dovecot a search is pretty fast _without_ using external indexes. I have a view defined (virtual plugin) with around 22.000 messages in it, and searching the full view only takes 2.5 seconds:
hmmm, could you please tell me more about your setup? What storage format do you use? Maildir or? What is the cumulative size of your messages?
My results without FTS on ZFS FS with SSD L2ARC are not so good:

Searching against "subject" is pretty fast, few miliseconds ...

With a current version of Dovecot a search is pretty fast _without_ using external indexes. I have a view defined (virtual plugin) with around 22.000 messages in it, and searching the full view only takes 2.5 seconds:
hmmm, could you please tell me more about your setup? What storage format do you use? Maildir or? What is the cumulative size of your messages?
Although the question was not formatted/quoted correctly I guess it is more towards myself as it explicitely speaks of a non-FTS setup:

The volume providing the mail root is using ext4 on an MD mirror (with CRYPT and LVM overhead):

I'm using unspectacular 7,200rpm SATA drives and mdbox.
Dear Thomas, You do seem to have some computing power. I think that does help. Thanks Kevin A.
