Hi there, i'm looking for someone to help us to optimise a internal search and creating a search result page
We want to exchange with you about a UX need on our search engine on our website

Today we have a internal search engine to search our trainings but the style made had problems :

We need to setup a search result page but the module used today seems very simple and don't offer the possibility .
