In both of these cases, then, understanding means attempting to extract indexes such that old stories can be related to new ones.

Is it the same as 'so that'?  Can I replace it with 'so that'?

Hi, Duaiekan—The meaning of "such that" there is "in such a way that." If you replaced "such that" with "so that," the meaning would be different; it would indicate that the purpose of attempting to extract indexes is to relate old stories to new ones. However, a paraphrase is possible with "so" and "that" separated:

• In both of these cases, then, understanding means attempting so to extract indexes that old stories can be related to new ones.

Thank you.  I have another question.

What about ' to the extent that'?  Is it possible there instead of 'such that'?

If you changed "such that" to "to the extent that," the meaning would change. The sentence is not talking about doing something to ever such an extent.
