I downloaded the [https://github.com/richardwilly98/elasticsearch-river-mongodb/downloads](https://github.com/richardwilly98/elasticsearch-river-mongodb/downloads) and tried the example: [https://github.com/richardwilly98/elasticsearch-river-mongodb/blob/master/README.md](https://github.com/richardwilly98/elasticsearch-river-mongodb/blob/master/README.md). It failed with on the following command: curl -XGET "[http://localhost:9200/testmongo/\_search?q=firstName:John](http://localhost:9200/testmongo/_search?q=firstName:John)" {"error":"IndexMissingException[[testmongo] missing]","status":404} Any idea?? I have set the mongodb replica set - so the oplog is present. Thanks for your help, Kara ---

I got it. I had to copy the river jar files into the elasticsearch-0.19.2/plugins/mongodb\_river directory and restart the elasticsearch. You need to create the plugins/mongodb\_river directory in the ES\_HOME. It is not there by default. Also, the query command should be curl -XGET "[http://localhost:9200/](http://localhost:9200/) mongoindex/\_search?q=firstName:John" It should be "mongoindex" not "testmongo". Just a minor change in the example Thanks, Kara On Apr 26, 3:35 pm, Kara [karine.marab...@aero.org](mailto:karine.marab...@aero.org) wrote: > I downloaded thehttps://github.com/richardwilly98/elasticsearch-river-mongodb/downloads > and tried the example:[https://github.com/richardwilly98/elasticsearch-river-mongodb/blob/ma](https://github.com/richardwilly98/elasticsearch-river-mongodb/blob/ma).... > It failed with on the following command: > > curl -XGET "[http://localhost:9200/testmongo/\_search?q=firstName:John](http://localhost:9200/testmongo/_search?q=firstName:John)" > {"error":"IndexMissingException[[testmongo] missing]","status":404} > > Any idea?? > > I have set the mongodb replica set - so the oplog is present. > > Thanks for your help, > Kara ---
