is there a way in sql server to define a table that it will be of type "dictionary" (where in dictionary i mean that the search of the text will be very fast like in a dictionary )
do you mean that you want to store text and search it or have a table where the contents are sorted? If it is the first then you need fulltext it it is the second you need a clustered index. Can you clarify what you want to do and what you want to store?
