I want to broaden the problem a little more.
For example, I have 10 flowers. I created a separate tab for each. General, maintenance, watering. Also, each tabs has been integrated into a separate wp-page with its own code. In this case I can only find a “Violet” page as far as the violet in the title. However, in tabs it should be written that the violet is a Magnoliophyta. I would like “Magnoliophyta” to result in violet even if it is included in tabs.
As there is no direct solution, the most logical solution would be to develop a separate search widget that contains all tabs. Or you need to index the content somehow.
With this development, I think the plugin can be used for many different purposes.
