You will need to send the following parameters in addition to the general parameters if you wish to pass product-click information:

Parameter		Description
query	essential	The search term for which the user has searched. In the context of a navigation click, the full category path should be sent as the query value.
pos	essential	The position of the product in the search results. The position is the absolute position. This means the first product on page 2 is number 11 if a search result page contains 10 products. The first product on page 1 is number 1.
page	essential	The number of the search result page on which the selected product was displayed. The first page has the number 1.
pageSize	essential	The number of products per search result page at the time the click was executed.
campaign	essential	A product contains the field `_FFCampaign_`, if it reached the search result via a campaign. This field has the campaign ID as its value. When interacting with this product you have to send this ID with the `campaign` parameter. This way it is possible to measure the influence of the campaign manager module.
