Smart / Federated Searches


Google Search Appliance
— has alerts
— PKI enabled

Google Mini
— no alerts

DeepWeb — This one might be a fit – it has an alerts feature

Carrot2 is a Results Clustering Engine — it groups searches into topical groups
— this is not a solution, but if we build something, it might be a part
— written in Java, but easily accessible from other languages

Microsoft FAST ES (was FAST Unity)

dbWiz — this is opensource, did not see alerts / repeatable searches
          — targeted at Libraries

WebFeat — seems very targeted to libraries
