We are using ES 1.2.2 server with a rails application as the client (ActiveRecord document model) and it seems as though some of the documents in the index might have been corrupted because the *id *field of the document is some garbled text like "JorMcjefSe2_VQkP_ntd8Q" when its supposed to be an Integer value based on the mappings.
As an example here is a document in the index with a corrupted id. Notice the corrupted document id, and the source id of the document is null curl -XGET http://localhost:9200/production_restaurants/restaurant/Gu-NGnHtR3ef4V2z4NfNsQ?pretty { "_index" : "production_restaurants_20140714222814907", "_type" : "restaurant", "_id" : "Gu-NGnHtR3ef4V2z4NfNsQ", "_version" : 1, "found" : true, "_source":{"_id":null,"_type":"restaurant","title":"Wreck Bar and Grill","address":"Rum Point","phone":null,"location_hint":null,"popularity":0,"votes_percent":null,"price":null,"city":null,"state":"KY","zip":null,"city_id":375,"neighborhood_id":54892,"activity":null,"location":{"lat":19.371508,"lon":-81.271523},"closed":false,"neighborhood":{"title":"Grand Cayman","id":54892},"cuisines":[],"tags":[],"dishes":[],"restaurant_path":"http://www.urbanspoon.com"} } It seems like the corruption might be around document deletion from the index because such indexed documents are no longer in our MySQL data which is the source for indexing documents in ES. Aside from finding what the issue might be with corruption, I am right now looking to find such bad documents in the index. I am finding no love with either a regex query <http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-regexp-query.html#query-dsl-regexp-query> or the missing filter <http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/_dealing_with_null_values.html#_missing_filter> which i apply them to the id field. Its a strange situation because *id *is of type *integer *in my index mapping i cannot apply regex query to it and get a NumberFormatException from Lucene. Any suggestion for a query that I could use to find such corrupted documents and remove them ahead of time. Right now I've had to be very reactive and remove these as I discover them my rails logs / error reports. Before I consider a full-reindex (which is heavy in of itself) I would like to explore what other options I have, including what might be the cause of these corruption. thanks - anurag -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
