For a use-case, I'll need to add and remove multiple documents to an elastic search index. My understanding is that the tf-idf or BM25 scores are affected by the frequencies that are calculated using the postings list (?)... But, if I add and remove many documents in a day, will that affect the document/word statistics?
I've already went though a lot of API's but my untrained eyes could not locate if this is the case, or if there's a way for me to force ElasticSearch to update/recompute the index every day or so...
Any help would be appreciated
