Search on other languages than Dutch much slower

Hi,

The Smart search system works in two phases:
- First, each time you save an item in the backend, the integration plugins for the Smart search system will provide the content to be searched to the Smart search system. The Smart search system will then process the content and store it in the database.
- Second, when a user uses the Smart search to search for something on the frontend, the Smart search will rely on its processed content in the database to provide the results.
What this means is that if the Smart search is slow when someone searches for something, the integration plugins are not involved. It's the Smart search system itself which is slow, and that's something we can't do anything about as it comes with Joomla.
It also means that you probably have a lot of content.
One thing you can try is to clear your Smart search index and reindex it. You can do that in the Smart search component, in your joomla backend. That way, if you have old entries that are not used, it will clear them up. It might be enough to fix the problem.

Regarding the warning, you can see that it comes from the "hikashop" plugin for the "gsd" system, and GSD stands for Google Structured Data. That's a third party extension and this hikashop plugin is developed by this third party extension. So you need to contact the developer of that extension directly if you want to report the warning as we can't do anything about it either.
