Question

I save 100.000 Vectors of in a database. Each vector has a dimension 60. (int vector[60])

Then I take one and want present vectors to the user in order of decreasing sim

Answer 1

In order to sort something, you need a sorting key for each item. So you will need to process each entry at least once to calculate the key.

Is that what you think of?

======= Moved comment here:

Given the description you cannot avoid looking at all entries to calculate your similarity factor. If you tell the database to use the similarity factor in the "order by" clause you can let it do all the hard work. Are you familiar with SQL?
