Re: Re: Re: Re: Re: seach for word "DNS" fails
If memory serves, it's possible that just because you have full-text enabled, doesn't mean Tiki is using it. It should in theory just work, but there could be an odd configuration of your MySQL database which prevents it from being used.
In addition, If I also recall correctly, different search modules invoke different search methods, did you try the refreshing of the indexes like I suggested, and also the clearing of the Tiki caches?
