As title suggests, I am missing the ability to clear all indexer search history at once, like it used to be. Now it is only possible to clear entries one by one.

It doesn't actually delete it, just hides it.

If you turn the option off, do a few searches and then turn it back on, the previous searches are still listed, minus the ones when it was off.

There should be an option to delete the search history.
