Here I'll present a simple full text search engine, that uses MongoDB as its backend. It's implemented using MongoEngine, and is intended as more of a proof-of-concept than a viable alternative to "real" search engines such as Solr, Sphinx, etc.

What will the search engine do?

The search engine will index documents in a certain MongoDB collection. Multiple fields may be indexed, and a weight may be assigned to each field. The words in each field will be split up and stemmed. A mapping between the words and the indexed documents will be stored in the database, and will be used when a query is run to determine the relevance of each document.
