ftAggregate ignores limit in options, or maybe i'm missing something #50
Description
Hello, I am trying to retrieve results with FT.AGGREGATE and I want to fetch all results with one query.
The task is, given one GPS point, sort all items (~1500) by distance around this point (coordinates of all items in index are different).
The problem is when I set limit in options to 1000000, I always get only 10 results instead of all.
The code is:
RediSearchAsyncCommands<String, String> rediSearchCommands = connection.async();
// RedisItem fields: String guid, Point coordinates
String indexName = RedisItem.class.getName() + "Idx";
String query = queryBuilder.build();
String longitude = "37.642042";
String latitude = "55.820642";
AggregateOptions.Builder<String, String> options = AggregateOptions.builder();
options.loads("guid", "coordinates");
String groupId = MessageFormat.format("geodistance(@coordinates, \"{0},{1}\")", longitude, latitude);
options.operation(AggregateOperation
.apply(groupId)
.as("distance"));
options.operation(AggregateOperation
.sort(Sort.Property.asc("distance"))
.build());
options.limit(0, 1000000);
String query = "(@coordinates:[40.790325734421394 42.71154290577113 8806301.180545114 m])";
rediSearchCommands
.ftAggregate(indexName, query, options.build())
.thenAcceptAsync((List<Map<String, Object>> results) -> {
Logger.logInfo("results amount = " + results.size());
});In Redis-stack monitor this native query is being generated:
"FT.AGGREGATE" "com.some_company.entities.RedisItemIdx" "(@coordinates:[40.790325734421394 42.71154290577113 8806301.180545114 m]) " "LOAD" "2" "guid" "coordinates" "APPLY" "geodistance(@coordinates, \"37.642042,55.820642\")" "AS" "distance" "SORTBY" "2" "@distance" "ASC"
The question is why LIMIT isn't set in native query? What I'm doing wrong?(
Maybe I need to use cursors or something?
