Hi,

I have written a Spring Boot based integration test where I use the bulk api to index some documents. This is the main loop of the `reindexAll()` method:

```auto
for (page in pageExports) {
            bulkRequest.operations { ops -> ops.index { it
                .index(Index.PAGE.indexName)
                .id(page.pageId.toString())
                .document(page)
            } }
 }
 val result = esClient.bulk(bulkRequest.build())

```

The result comes back just fine and the `took` field has the value 16. My understanding was that this call is blocking. (E.g. the request only returns when all the documents have been ingested).

However right after I do the result when I do a count query on the index like so:

```auto
val result = esClient.count { it.index(listOf(DwIndex.PAGE.indexName))}.count()

```

I get 0 as a count, same if I fire a search query. If I wait on breakpoint after the indexing and before the query, or if I put a `Thread.sleep(100)` in front of the count/search, it is correct.  
So my question is what is happening here? Possible explanations that came to mind:

- Bulk is indeed asynchronous, which doesn't make a lot of sense since it has the errors for documents that could not be indexex
- Bulk is synchronous, but after the indexing, it takes some (small amount of) time for the newly indexed documents to be pushed to the shards.
- I'm doing something wrong 🙂

What would be a good way to make `reindexAll()` block until everything is ready, so the contract should be if you call `reindexAll()` you can instantly start searching. I would not like to add a `Thread.sleep()` or poll with a search request at the end of the method.

Cheers and thanks!

Welcome!

Don't forget to call `refresh` before counting/searching.

See

> <https://github.com/dadoonet/elasticsearch-java-client-demo/blob/be89f7cc7530cebfaeadc7c5e9bf109c71ee4caa/src/test/java/fr/pilato/test/elasticsearch/hlclient/EsClientIT.java#L396-L419>

Specifically this line:

```auto
client.indices().refresh(rr -> rr.index("bulk"));

```

Thank you a lot for the quick reply. That fixed my issues. Also thanks for linking the tests, that will be helpful in the future as a reference!

Cheers
