/**
 * The parameters apply in the following preference order:
 *  - Highest priority: Tag & date (or date range)
 *  - Month (and Year)
 *  - Pagination
 *
 * So, when the user click on a tag link, the pagination, and month will be reset, but not the date filter. Also,
 * changing the date will not affect the tag, but will reset the month and pagination.
 *
 * When the user clicks on a month, pagination will be reset, but tags retained. Pagination retains all other
 * parameters.
