Re: keywords

["Alexey Parshin" <alexeyp@gmail.com>]

My idea for such interface was really simple. There should be a call of appropriate reindex() procedure in a trigger on insert, update, or delete any content.
It should update the list of keywords for the content.

All right, so it is wise to prepare an interface for ever developing
search procedures leaving implementation for future versions?
