I am using meta_search plugin开发者_如何学运维 with my rails3 app for search functionality. When I want to try the search method of meta_search plugin on my model in console, it gives me this error. I am not able to figure the error from the plugin source code.

A little late to this party but you shouldn't be supplying the parameter as an array.

Listing.search(:address1_starts_with => "lucky")

should do the trick.
