Can't get vectorStoreTest with MongoDBAtlasVectorStore to work locally

Bug description
I am having trouble with MongoDBAtlasVectorStore. Basically when I copy and paste this into my project because the similarity search isn't working...

List<Document> ds = List.of(
                new Document(
                        "Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!! Spring AI rocks!!",
                        Collections.singletonMap("meta1", "meta1")),
                new Document("Hello World Hello World Hello World Hello World Hello World Hello World Hello World"),
                new Document(
                        "Great Depression Great Depression Great Depression Great Depression Great Depression Great Depression",
                        Collections.singletonMap("meta2", "meta2")));

        vectorStore.add(ds);
        Thread.sleep(25000); // Await a second for the document to be indexed

        List<Document> results = vectorStore.similaritySearch(SearchRequest.query("Great").withTopK(1));

The result I see is not correct...

Environment
Java 23
Spring AI 1.0.0-M3

Steps to reproduce
See repo here. You can add the code above to that and see it doesn't work

Expected behavior
I would expect it to return a document as it does in the test.

Minimal Complete Reproducible example
See above more available here

Got debugging into source working now trying to understand why the query is returning 0 records. Also running the build locally with mvn clean install to make sure it isn't an environment issue.

It seems that the way the vector store is working isn't allowing me to aggregate properly. I added a script

https://github.com/jrgleason/spring-ai-example/blob/ADD_MQTT_SUPPORT/app/debug/mongodb/test-count.js

That seems to confirm this can someone see what I am doing wring with my config?
