Examples of org.jboss.dna.graph.search.SearchEngineIndexer

org.jboss.dna.graph.search.SearchEngineIndexer
A utility class that can be used to update the indexes of a search engine by crawling parts of the source. Each instance is created to make a series of atomic updates to the search engine using a single connection to the source.

        indexer.close();
    }


    @Test
    public void shouldReIndexRepositoryContentStartingAtNonRootNode() {
        SearchEngineIndexer indexer = new SearchEngineIndexer(context, engine, connectionFactory);
        indexer.index(workspaceName1, path("/Cars"), 10);
        indexer.index(workspaceName1, path("/Cars"), 10);
        indexer.index(workspaceName1, path("/Cars"), 10);
        indexer.close();
