Drupal search not working completely

Hy,

I have a problem with Drupal research.
In the search administration (/admin/config/search/pages), the indexing is well at 100%.

However, some words on the site do not return any results (e.g. egalim).

The words are in the search_index and search_dataset table, but no entry in the search_total table.

Can you help me?

Thanks
