Returning multiple items of the same type is not always ideal for search results. For example, let's say that you have a Model 1 category for ten different sizes of a MDL1 item and, instead of putting each size on its own page, you have them all on a single page like the below:
So, with this in mind, when you search for MDL1, you would presumably want it to return the MDL1 category instead of it returning ten different individual item page links. Now imagine if you have twenty sub-items for this category. Or fifty.
To cause an item search to return a category instead of an actual item, you should do the following:
- Set a document layout to Roll Up Search Results
- Set the page at the top of the model hierarchy that you want to be returned in searches to use that layout
- Configure the roll-up search results job to turn off search permissions on pages/items below that page to keep them from showing in the search results as well as copy item attribute data into the top-level page so it still will return for searches appropriately
