Implement site search with type ahead (OpenSearch) #7876
Description
Describe feature
would be great if you can implement opensearch. When you setup Trilium as site search in Chrome, you would already see the best hits while typing ahead. I like this feature in raindrop.io and would love to see in Trilium.
This would be an enhancement of using {baseurl}/#?searchString=%s as site serach in Chrome
