Thanks. I've already deactivated other search plugins. We are creating everything from a scratch with elementor using "hello elementor".
I'll install the patch asap and I'll let you know.

@EpsilonAdmin Hi. I have the same infinite indexing problem with the v2.49.200 on wp 6.3.1 (maria DB) and....Elementor. I have even a problem on the front-end: the PDFs are not shown.

• list item I have already installed the "patch" for elementor - wpfts-addon-elementor

• list item I have already checked the PDFs on the media gallery and they're all correctly extracted without any error.

• list item if I use the "test search" from the plugin options, it correctly shows the PDFs: the problem is just on the frontend. (Unfortunately the website is in maintenance mode and I can't put it live, so the link would be useless)

• list item I previously used Algolia, but I already deactivated the (unofficial) plugin and reset all the previous setup.

Are the 2 problems (indexing and frontend) related? If not could you please try to solve both the issues?

Thanks
