In addition to its “physical” on-page constructions, each search tab also has an active search-tab configuration, which controls many aspects of the way various Ontolica Web parts will behave and can also modify the result list by, for example, adding implicit search terms and/or scopes. Each search tab is associated with a specific search and result page; it may also have an advanced search form.
Any page that includes an Ontolica Web part will always have a search-tab configuration that applies to the Ontolica parts on it. Even if a given search form and/or result page does not look like it has any “tabs” on it, a search-tab configuration will still be in effect to establish configuration settings for the Ontolica parts. This means that “search tabs” are not an optional navigation feature for Ontolica, but are in fact the foundation on which much of the basic Ontolica functionality is built and managed.
