The Smart Search Plugin integrates with the Joomla Search component (com_finder) and finds images.
It indexes the following fields:
Defines the size of the thumbnails which are delivered into the search result. Valid values: numbers.
Open images in lightbox
The link in the search results opens usually the event. Using this open, you can open the lightbox on the event page and show the image directly.
If you sync your file system with the database or change the search plugin configuration, make sure you rebuild the search index manually.
Thumbnail in Search results
With Joomla 4, it is only a simple configuration option of the Smart Search to let thumbnails appear in the search result.
With Google Photos, the images in the search result will not appear. This is on purpose. The thumbUrls are stored in the search database but are valid only a couple of minutes. If Google Photos in the search results is something you can’t live without, contact me. Until then, it works with all other picture sources.
