In case you don’t specify an index, the node will search across all available indices using
_all (see documentation). Anyhow, ES will just ignore the index field and return matching documents according to your query from the pool of all documents. It will not query each index individually on its own.
From what I understand, the following is exactly what you want to achieve: Execute a query individually against 10+ indices and concatenate the results of each individual query (instead of a combined one).
The ES Nodes currently do not support this. Anyhow you can easily solve this with a loop:
- Prepare your ES search with
Elasticsearch Search and
Elasticsearch Query nodes
- Fetch all available indices via the
Elasticsearch Console node from endpoint
- Loop over each index, add the index via flow variable to
Elasticsearch Index and execute the query via the
I uploaded an example workflow to my NodePit Space. You might not be able to run the workflow (as it uses a local cluster on my machine), but it should give you a good idea what I actually described above.
Does this help you? Please let me know if you struggle somewhere.
