Does elastiknn supports index patterns ?

[flo-dhalluin]

Hi,

I would like to use the "index patterns" feature of ES, say creating a daily index named "vectors-YYYY-MM-DD" with and associated index template mapping : "my-vectors-mapping"
{
"patterns": ["vectors-*"],
"mappings": {
...
"v": {"type": "elastiknn_dense_float_vector", "elastiknn":{..}}
}
}

From my first tests, it seems that the index template is not correctly applied to created indexes, thus knn search on /vectors_*/search fails.

Such a pattern would allow me to quickly expire data from the db by deleting "old" indexes.

Thanks !

Hi, I've never used index patterns. I also don't remember seeing anything related to index patterns while implementing the plugin.

How exactly is it failing?

It seems that the mapping is not applied to dynamically created indexes ( I see all the mappings defined in the template applied to the fields, except the one for the elastiknn vectors ... ).
And a nearest neighors query on /vectors_*/search leads to a crash ...

Got it. Can you please post the error you're getting when you search? I'll open an issue.
