Search Service

The Bloomreach Experience Manager Search Service

The Bloomreach Experience Manager Search Service allows one to build queries using a Java DSL. A brief preview assuming the namespace of your project is myproject.

Search fluent API example:

import org.onehippo.cms7.services.search.service.SearchServiceFactory;
import org.onehippo.cms7.services.search.service.SearchService
import static org.onehippo.cms7.services.search.query.QueryUtils.both;
import static org.onehippo.cms7.services.search.query.QueryUtils.date;
import static org.onehippo.cms7.services.search.query.QueryUtils.either;
import static org.onehippo.cms7.services.search.query.QueryUtils.integer;
import static org.onehippo.cms7.services.search.query.QueryUtils.not;
import static org.onehippo.cms7.services.search.query.QueryUtils.text;

public class SearchExample {

   public void doSearch() throws SearchServiceException, RepositoryException {

        SearchServiceFactory searchServiceFactory =
                HippoServiceRegistry.getService(SearchServiceFactory.class, SearchServiceFactory.class.getName());
        if (searchServiceFactory == null) {
            throw new SearchServiceException("Cannot find search service factory by name " + 
                                              SearchServiceFactory.class.getName()); 
        }

        SearchService searchService =
                searchServiceFactory.createSearchService(UserSession.get().getJcrSession());

        Query query = searchService.createQuery()
                .from("/content/documents")
                .ofType("hippo:document")
                .where(text("myproject:title").contains("hippo"))
                    .and(date("hippostdpubwf:publicationDate").from(new Date()).andTo(new Date()))
                    .and(integer("myproject:counter").from(6).andTo(8))
                    .and(not(text("hippostdpubwf:lastModifiedBy").isEqualTo("editor")))
                .limitTo(10)
                .offsetBy(30)
                .orderBy("hippostdpubwf:publicationDate").descending();

        QueryResult result = searchService.search(query);
        HitIterator hits = result.getHits();
        while (hits.hasNext()) {
            Hit hit = hits.next();
            String id = hit.getSearchDocument().getContentId().toIdentifier();
            Node documentNode = UserSession.get().getJcrSession().getNodeByIdentifier(id);
            // do stuff

        }
    }
}

The fluent API will guide you through the different parts of the query. A number of static helper methods (text, date, not, ...) is available to keep the constraints readable.

Note that there's no JCR code involved; this is intentional as the API is intended to support multiple implementations.

Configure the Search Service

As of Bloomreach Experience Manager 11.2, the Search Service is a configurable module, with the following configuration location in the repository:
