Problem with filtering and pagination

I have a problem when filtering a table via a link:

I have two tables. When I click on a column in the first table then a second table is shown which displays information for that column only. Using the suggestions in this forum I have succesfully implemtented this, using the following custom ID:

http://localhost/joomla/index.php?option=com_content&view=article&id=2&aso=exact&data_search=id||name||date_created||exam_id|@ID

This works well if there is only one page in the resulting table. However if there are multiple pages and I click next, the "exact" argument somehow gets lost. So for example if I filter for "exam_id=1" then all columns containing the number 1 are shown when I go to the second page (like 10, 21, etc.).

If I set the "Default search option" to "exact" in the backend everything works, but that is not something I want to do.

Am I doing something wrong, or is there a way to fix this?

Thanks!

No when I show the advanced search options it works.
Thanks!
