Hi,
we have many indexes each with one or more aliases each with one shard and
each created from same template.
I want to fire scroll search with limit to one or more indexes by one or
more aliases. If I set a size parameter its applied to result from a shard
not to whole result which i've expected. If i set a post limit filter then
no data are returned.
I want to set size to ONE and get ONE result even if i hit a 15 shards. Now
i gets 15 results or nothing.
What's wrong?
String[] aliases = getAliases(input);
SearchRequestBuilder requestBuilder = esConnection.prepareSearch(aliases);
BoolQueryBuilder boolQuery = boolQuery();
boolQuery =
boolQuery.must(rangeQuery("created_time").from(input.getTimeFrom()).to(input.getTimeTo()));
...
requestBuilder.setQuery(boolQuery);
requestBuilder.setSearchType(SearchType.SCAN);
requestBuilder.setTypes("type");
requestBuilder.addSort("created_time", SortOrder.DESC);
requestBuilder.setExplain(false);
requestBuilder.setFetchSource(false);
requestBuilder.setNoFields();
requestBuilder.setSize(input.getLimit());
//
requestBuilder.setPostFilter(FilterBuilders.limitFilter(input.getLimit()));
requestBuilder.setScroll(new TimeValue(1, TimeUnit.MINUTES));
ListenableActionFuture execute = requestBuilder.execute();
SearchResponse searchResponse = execute.actionGet();
searchResponse =
esConnection.prepareSearchScroll(searchResponse.getScrollId())
.execute().actionGet();
SearchHits hits = searchResponse.getHits();
List result = new ArrayList<>();
for (SearchHit searchHit : hits.getHits()) {
result.add(searchHit.getId());
}
