This package contains classes that you can subclass and register to
            lookups of nodes if you want to specify how the nodes should be
            searched. For this, use
            SearchInfoDefinition
            or SubTreeSearchOptions,
            and possibly SearchFilterDefinition
            and SearchInfoDefinitionFactory.
        
            To add a custom search scope to Find in Projects dialog,
            you will need to subclass
            SearchScopeDefinition
            and SearchScopeDefinitionProvider.
