This depends on the algorithm. Some information retrieval algorithms just work with boolean values, others keep track of the frequency of a term in a document.

If you want to keep track of the frequencies, you can either store position/frequency pairs or use two lists, one for the position, the other for the frequencies. The former approach is cleaner, the latter should be faster.

Hope this helps, -gjb-
