Example 2 with EmptyParameterError

use of org.graylog.plugins.views.search.errors.EmptyParameterError in project graylog2-server by Graylog2.

the class MoreSearch method scrollQuery.

/**
 * This scrolls results for the given query, streams and time range from Elasticsearch. The result is passed to
 * the given callback in batches. (using the given batch size)
 * <p>
 * The search will continue until it is done, an error occurs or the search is stopped by setting the
 * {@code continueScrolling} boolean to {@code false} from the {@link ScrollCallback}.
 * <p></p>
 * TODO: Elasticsearch has a default limit of 500 concurrent scrolls. Every caller of this method should check
 * if there is capacity to create a new scroll request. This can be done by using the ES nodes stats API.
 * See: https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-scroll.html#scroll-search-context
 *
 * @param queryString    the search query string
 * @param streams        the set of streams to search in
 * @param timeRange      the time range for the search
 * @param batchSize      the number of documents to retrieve at once
 * @param resultCallback the callback that gets executed for each batch
