What is the best strategy for selecting mongodb entries in which a string value contains a set of words or phrases? I’m thinking of something equivalent to mysql’s LIKE function, e.g.
WHERE (TEXT LIKE "% apple %") or (TEXT LIKE "% banana %")
I’ve seen options that involve tokenizing the string, but this would involve building unigrams for all the text, which would be huge no?
MongoDB has no full text search capability right now, but it’s easy to use external search engines like SOLR.
I strongly discourage you trying to rebuild text search with Regex or word stemming etc. yourself. You should rather focus on your app own features 🙂
I am using this combination: Mongoid, Sunspot and Mongoid-Sunspot. It works very well in production, and development setup is easy.
