Olivier, there is no way to pass Workflow the results from your search in the client. If the search will always be the same, you can create a "Business Process" workflow with the search already formulated in workflow and allow the user to trigger the Business Process from the client, but that would be the closest that you could get to it.
Workflow is a server side service that interacts mostly with the repository and not the user. The exception to this is the Business Process, and again there is limited user interaction directly with workflow but rather that interaction is mostly through entries in the repository and not the client application directly with workflow.
