TODO:

Complete the https://github.com/toastdriven/django-haystack/ implementation to allow search through

• code and link submissions (description text, title text, URL text)
• tags,
• user profiles text
• comments (in the future)

Sanitize the description fields from markup. See previous sanitize_search_text(...) function in ucomment.

Alternatives considered, but not going to be used

• https://bitbucket.org/mchaput/whoosh/wiki/Home

Enhancement: have advanced search options

• Tags tag:matrix or tag: "data analysis"
• By author: author:sam or author:"George Samuels"
