Full text search options for MongoDB setup

Question

We are planning to store millions of documents in MongoDB and full text search is very much required. I read Elasticsearch and Solr are the best available solutions for full

Answer 1

MongoDB can't do efficient full text search. You can do wildcard searches on fields, but i don't think these use indexes efficiently.

I would recommend using the river functionality of ElasticSearch to automatically push the documents from MongoDB to ElasticSearch.

elasticsearch-river-mongodb is a MongoDB to Elasticsearch river that when a document changes in MongoDB, ElasticSearch will monitoring the oplog and then automatically update its index.

This minimises the problem of keeping the two datastores in sync, as ElasticSearch is just monitoring the replication tables of Mongo.
