As reported on Textmining, Gartner's report on enterprise search has been published, under a new name: information access technology. The report forbids reproduction, so I'll summarise - information is complex and keyword search isn't going to cut it. To properly describe the complexities of the data and the complexities of the user's intentions greater vision is required wrt interfaces and visualizations of results.
I find this resonates with my opinions about the cult of simplicity that Google perpetuates. While it is true that simplicity makes sense in consumer facing products, there is no denying the complexity of the data - human and other documents - on the other side of the wall. Due to the complexity of the data, the complexity of the user's intention needs to be acknowledged. This can either be done via a more complex interface, or, with a more sophistication, via a natural language interface and with capabilities beyond text mining - what I am starting to think of as language mining - applied to the data in the index.
[Briefly, language mining is like text mining, but with equal emphasis on world knowledge, linguistic knowledge and data mining methods - a topic for a later post.]
