The History Panel will display searches as either "search groups" or as "search items." The key is how many reports are generated due to how many different products are represented in the investigative or order search group.
A search group contains reports for searches from one or more products. For example:
If a Search List contains searches for a subdivision, an arb and a general name, there will be one report group (as all these parameters are from the title product).
If the Search List contained all the above plus one or more tax parameters, the search group would have two reports groups (one for all the title parameters and one for all the tax parameters).
A search item would be a general name search with nickname and soundex results is one report. A search item can be within a search group or independent of a search group.
