Hi All, I recently have been working on a Mongoose plugin to index MongoDB documents in Elasticsearch and wanted to use the same IDs across both but ran into some errors. I'll be able to investigate further when I get home as I don't recall the exact error but I am wondering if anyone has experienced this? For now I just store the MongoDB id as \_mongoId in the elastic search document. Thanks, James ---

You should be able to simply store the mongo id it as a string...

To quote what has probably been said may times on the internet, "I was doing it wrong." 🙂 Thanks, James On Thu, Jun 21, 2012 at 11:11 PM, benny.sadeh [benny.sadeh@gmail.com](mailto:benny.sadeh@gmail.com) wrote: > doing the very same thing and haven't bumped into any problems. > can you be more specific about what sort of problems are you running into? > > On Tuesday, June 19, 2012 9:53:00 AM UTC-7, James Carr wrote: > > > Hi All, > > > > I recently have been working on a Mongoose plugin to index MongoDB > > documents in Elasticsearch and wanted to use the same IDs across both but > > ran into some errors.
