What options do we have to customize the way our online catalog search works?

For the catalog search, there are no additional settings that can be applied to it, however, when searching, the item type can be narrowed down with the toggles shown here:

For the information that is searched, the catalog search will search on the following fields only:

• Title - must use api key title
• Code - must use api key code
• Group Filter 1 - must use api key groupfilter1
• Description - must use api key description

The search will treat any phrase entered into it as if it already has quotes, so it won't be able to specify any further than that. Combining key words with a + doesn't yield better results as it will search each item separately.
