It's a nice hack, but I'd rather just use Elasticsearch and try out the MongoDB river (https://github.com/richardwilly98/elasticsearch-river-mongodb https://github.com/richardwilly98/elasticsearch-river-mongod...). There is a reason why Lucene exists. You'll gain insertion speed, use less RAM for your active working set with MongoDB, and gain TONS of features.
