Elastic search has less results than lucene

Elastic Stack Elasticsearch
1

Hi,

I index 1 million pages in lucene and the same pages in elasticsearch.

In elasticsearch I get 5 to 10% les results (the results I do get are the
same in elasticsearch as with lucene).

How can I check the reason for the differences?

Thanks,

Ophir

Unless you provide more insight in what you are doing, the query you are
running and how you analyze things I don't think anybody will / can help
you here.
There are so many moving parts here, by all means I would guess the problem
is in your code ie. you are not comparing apples and apples.

that said, I am happy to help you either way. you can also share your code
maybe on github or so?

Issue solved. The problem was that the document id at elasticsearch was a
bit (logically) different than the one used as lucene document id. So some
of the indexed data at ES was overridden when doc id repeated itself.
Thank you Simon
