  • bundle exec rake ts:index (index your data)

  • bundle exec rake ts:start

  • Switch method in plugin configuration.

Difference between search engines

Main adventages of SphinxSearch is fact that if you set many words to searching this gives you results faster then SQL Engine.

* SQL Engine: Takes words 1:1 if you match 'GUI Changes' this will be looking for “GUI” “Changes”.

* Thinking Sphinx Engine: Firstly search for words 1:1 after this substrac last character ex. like: “Running”

- Firstly "Running" 
- "Runner"
- etc.
