  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.
  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.

Risk changing MySQL ft_min_word_len

eugenevdm

Regular Pleskian
I would like to know if there is any risk invovled in changing the default mysql setting "ft_min_word_len" from it's default of 4 to 2. As far as I now this is the minimum word len search.

What is the risk? Will the server take longer to run querries, is there a significant performance impact, etc.?
 
Shouldn't be an issue, full text indexes will be a little bigger, but I think you would be fine.
There are a lot of 2 letter words that you really might not want to index, so I've changed mine to 3 and it works great.
I also disabled the "noise" list for Mysql so things like "first", etc would not be ignored.
 
Where is ft_min_word_len line on Server

Hello,

I edited my.cnf file and restarted the mysqld server, but it doesn't work.

I need to enter > ft_min_word_len=3
so that 3 chr. search will work

Where on the server is > ft_min_word_len=4
in which file path?
I am using Centos 5, Plesk 8.4.0

Thanks!
