this test only tests whether it can create the index with the mapping but does not verify whether that actually works. as shown in #437 it currently adds something which it shouldn't and thus searching documents fails afterwards. i think it'd be great if this test here could cover that (in which case it'd currently fail until opensearch-project/opensearch-java#1513 gets resolved)

@rursprung updated the tests but I have troubles reproducing the failure, could you please help me to craft it properly? Thank you.

hm, interestingly enough i just created a test case which fails for both ORHLC and OSC (which isn't the bug which i had reported) 😅:

in DynamicTemplatesContextBaseTests:

    @Test
    void shouldCreateDynamicTemplateWithDots() {
        IndexOperations indexOperations = operations.indexOps(SampleDynamicTemplatesEntity.class);
        assertThat(indexOperations.createWithMapping()).isTrue();

        operations.save(new SampleDynamicTemplatesEntity(Map.of("A.B", "Smith")));
        assertThat(operations.search(Query.findAll(), SampleDynamicTemplatesEntity.class).get().count()).isEqualTo(1L);
    }

the only change compared to shouldCreateDynamicTemplateOne is that i replaced "John" with "A.B" which is reasonable and to be expected?

since i can't push to your branch i created #446 to show a test which actually fails. note that you have to remove the @DisabledIf annotation to see the failing test

@rursprung No, this is not supported: the values with dots are not accepted to object fields (but to nested or flattened fields), traced it back to https://www.elastic.co/guide/en/elasticsearch/reference/2.4/dots-in-names.html

i've ported this over to opensearch-java, see opensearch-project/opensearch-java#1929
