I want to implement a search solution for a website written in Django. From the available options (I have researched Solr, Sphinx, Xapian, PostgreSQL/Tsearch3, MySQL) Sphinx looks like the nicest. However, it does not support stemming for Polish, and that is the language of the data that I want to make searchable.
What are the best ways of dealing with unsupported languages in Sphinx? I have an intuition that I could create a stemming corpus from the Ispell dictionary. How can I make that work with Sphinx?
