Is it possible to customize Alkaline's search results display format, look and feel?

This is one of the main design goals in Alkaline. You can fully customize results. This means that Alkaline provides an expressions mechanism for any type or kind of results. You can produce a layout that fits exactly into your site and users will not suspect that they are actually querying an Alkaline server.

You can have many layouts for different configurations and have a single database searched with many different templates. Thus, you can run the same search engine over multiple sites.
