It seems that you are using one of our e-commerce integration (Wordpress or Magento maybe?). If that’s the case, could you please tell us each and the version you are using?
If this is a custom integration, you should have a look at our snippeting documentation. Snippeting is a way to truncate a long text after a defined number of characters in an intelligent manner (not cutting in the middle of a word, and adding an ellipsis (…) after it).
You can also handle that through CSS directly for the display, as it has a nice text-ellipsis feature that can correctly fit the size of its container.
As for the Algolia logo, it will depend on which plan you use. If you’re on one of the community (free) accounts, you’ll have to keep the logo next to the search results. If you’re on one of the paying account, you can remove it.
