I have 2 questions about retrieval and scoring,
How deep when ES retrieving documents, even without scoring? By now the information I got was all. please help me to ensure this mechanism. Actually when I was developing a web search engine, normally the retriever would interrupt when it thinks there are "enough good" candidate documents for this search, likely, just top10 in 10,000 docs.
The search result ranking for one same query on one static index, stable or not? For most times it is stable, but sometimes ES returns different results, I was guessing this is caused by some bad shards, but not sure. Any help?
Thanks all ^.^
