Class AbstractOmniSearchHandler

  • All Implemented Interfaces:
    OmniSearchHandler, javax.jcr.observation.EventListener
    Direct Known Subclasses:
    FormsAbstractOmniSearchHandler
    public abstract class AbstractOmniSearchHandler
extends java.lang.Object
implements OmniSearchHandler, javax.jcr.observation.EventListener
    AbstractOmniSearchHandler is an abstract class which other can extend to provide implemenation of OmniSearchHandler If any Module implements OmniSearchHandler using AbstractOmniSearchHandler , It needs to create contentNode under path METADATA_PATH. And provide all the property details in that Node.

    Properties:

    IS_SUGGESTABLE_PROPERTY
    Property that decide if Predicate should be used in predicate suggestions
    METADAT_PATH
    PATH where metadata of all the modules will be stored
    NODE_TYPE_PROPERTY
    Resource type of Module (eg. dam:Asset)
    OPTION_PATH_PROPERTY
    optionPath property of a Predicate
    PREDICATE_PATH_PROPERTY
    property that stores Predicate Path in METADATA Node
    DEFAULT_SEARCH_PATH_PROPERTY
    property that stores Default Search Path in METADATA Node
    PREDICATE_TYPE_PROPERTY
    property that identifies type of Predicate

      • getSuggestionQuery

        public javax.jcr.query.Query getSuggestionQuery​(ResourceResolver resolver,
                                                java.lang.String searchTerm)
        This function returns Query that provides suggestions based on parameters provide in the request. It will look for "fulltext" paramter in request and "fulltext" parameter will treated as search term. Based on this search term suggestion query will be created.
        Specified by:
        getSuggestionQuery in interface OmniSearchHandler
        Parameters:
        resolver - ResourceResolver instance
        searchTerm - text term for which suggestions are require
        Returns:
        Query that returns suggestions on execution

      • getPredicateSuggestions

        public java.util.List<PredicateSuggestion> getPredicateSuggestions​(ResourceResolver resolver,
                                                                   I18n i18n,
                                                                   java.lang.String searchTerm)
        This function provide List of Predicates that matched to current request parameters. It will match the value of PredicateSuggestion to the search term. Currently predicate suggestion works only if length of search term is more than MIN_SUGGESTION_REQUIRE_SIZE
        Specified by:
        getPredicateSuggestions in interface OmniSearchHandler
        Parameters:
        resolver - ResourceResolver instance
        i18n - I18n instance
        searchTerm - text term for which suggestions are require @return List of PredicateSuggestion
        Returns:
        List of Predicates

      • getSpellCheckQuery

        public javax.jcr.query.Query getSpellCheckQuery​(ResourceResolver resolver,
                                                java.lang.String searchTerm)
        This function returns Query that provides spell check suggestions based on parameters provide in the request. It will look for "fulltext" paramter in request and "fulltext" parameter will treated as search term. Based on this search term spell check query will be created.
        Specified by:
        getSpellCheckQuery in interface OmniSearchHandler
        Parameters:
        resolver - ResourceResolver instance
        searchTerm - text term for which suggestions are require
        Returns:
        Query that returns spell check suggestion on execution.

      • getModuleConfig

        public Resource getModuleConfig​(ResourceResolver resolver)
        Return the moduleConfiguration resource for this handler.
        Specified by:
        getModuleConfig in interface OmniSearchHandler
        Parameters:
        resolver - the resourceResolver to use
        Returns:
        the resource where the configuration is stored.

      • init

        public void init​(ResourceResolver resolver)
        Deprecated.
        Use initialize instead.
        This function intialize the ResourceResolver instace. It usually called on activation of OmniSearchHandler or on event from implementation of OmniSearchHandler
        Parameters:
        resolver - ResourceResolver instance, AbstractOmniSearchHandler expects that this ResourceResolver will not be closed before deactivation.

      • initialize

        public void initialize​(ResourceResolver resolver)
        initialize the AbstractOmniSearchHandler.
        Parameters:
        resolver - a ResourceResolver to read the relevant information from the repository. After calling this method the resolver can be closed, it's not expected to keep it open.

      • destroy

        public void destroy​(ResourceResolver resolver)
        Deprecated.
        Removed without replacement (it always was an empty method)
        This function clear the predicateSuggestionList and remove all the eventListeners. This is usually called on deactivation of OmniSearchHandler
        Parameters:
        resolver - ResourceResolver instance
