Hi all,
I'm running an ecommerce site with elasticsearch and want to add a "new
items this week" feature.
I need to add a creation date for every document, but I cannot make it work.
The situation is as follows:
1. The products of the site are imported every day using a JSON datafeed
2. The import of the next day will overwrite the old products/documents in
ES
What I've tried:
1. Enabled the \_timestamp field. This added a timestamp field, but every
day when the datafeeds are imported, it is overwritten. This is the case
for client.prepareIndex() and client.prepareUpdate()
2. Used the 'upsert' command to add a creation date. Since I do not know
which product is updated/deleted or new in the feed I also have to use
doc\_as\_upsert. The result is that the upsert command is not executed.
3. I cannot add the creation date to the product myself, since everyday all
the documents in the index will be overwritten when the datafeed is
imported.
My Question: Is it possible to have a creation date of a document persist
on updates?
I'm using Elasticsearch version 0.90.5
Regards,
Dennis
