I am able to find an object with a datetime range corresponding to 2022-07-27 when sending the following HTTP requests from Postman to an Elasticsearch 8.3.2 server.
PUT http://localhost:9200/commit
{
"mappings": {
"properties": {
"dateTimeRange": {
"type": "date_range",
"format": "uuuu-MM-dd[['T'][ ]HH:mm[:ss[[.][,][SSS][SS][S]]]][XXXXX][XXX][X]"
}
}
}
}
PUT http://localhost:9200/commit/_doc/commit20220727?refresh
{
"dateTimeRange": {
"gte": "2022-07-27T00:00:00.000Z",
"lte": "2022-07-27T23:59:59.999Z"
}
}
PUT http://localhost:9200/commit/_doc/commit20220728?refresh
{
"dateTimeRange": {
"gte": "2022-07-28T00:00:00.000Z",
"lte": "2022-07-28T23:59:59.999Z"
}
}
POST http://localhost:9200/commit/_search
{
"query" : {
"range" : {
"dateTimeRange" : {
"gte": "2022-07-27T12:12:12.999Z",
"lte": "9999-12-31T23:59:59.999Z"
}
}
}
}
That being said, I am unable to use the Elasticsearch Java API Client and the query datetime:[2022-07-27T12\\:12\\:12.121Z TO *] to find an object with a date range corresponding to 2022-07-27.
In ElasticsearchIndexerAndQuerierTest.java, the code on line 158 under comment Attempt to search for commits with specific dateTime ranges yields the assertion error expected:<2> but was:<0>.
How do I resolve this assertion error?

CodePudding user response：
PutMappingRequest.source sets the _source property of the mappings, which is not what I wanted. My goal was to set the entire mappings from JSON, which can be done using PutMappingRequest.withJson.
The section of code from SourceField.Builder... to System.out.println(putMappingResponse); should be replaced with the following.
PutMappingRequest.Builder putMappingRequestBuilder = new PutMappingRequest.Builder();
putMappingRequestBuilder.index("commit");
String mappings =
"{\n"
" \"properties\": {\n"
" \"id\": {\n"
" \"type\": \"text\"\n"
" },\n"
" \"name\": {\n"
" \"type\": \"text\"\n"
" },\n"
" \"dateTimeRange\": {\n"
" \"type\": \"date_range\",\n"
" \"format\": \"uuuu-MM-dd[['T'][ ]HH:mm[:ss[[.][,][SSS][SS][S]]]][XXXXX][XXX][X]\"\n"
" }\n"
" }\n"
"}";
putMappingRequestBuilder.withJson(new StringReader(mappings));
PutMappingRequest putMappingRequest = putMappingRequestBuilder.build();
PutMappingResponse putMappingResponse = client.indices().putMapping(putMappingRequest);
System.out.println(putMappingResponse);
