Question

I’ve been trying to get Thinking Sphinx for Ruby to handle prefixes and/or star, and every time i generate a new configuration file, it seems to ignore it.

Here’s the line I added:

define_index do
    [... Stuff ...]
    set_property :min_prefix_len => 1
end

And then I run:

rake ts:config
rake ts:in
rake ts:run

And nothing new. I keep checking the config file, and it never changes due to this. I even manually go in and change the file, and then in is replaced with a file without anything relating to min_prefix. Any thoughts?

Edit —

I don’t have a .yml file right now.

Answer 1

The answer to the question ended up being:

-Upgrade to more recent version of TS – older versions (<1.3.14) do not support multiple indexes

-The define index blocks need to be setup like this:

  define_index 'library_index' do
     [...]
  end

  define_index 'prefix_library_index' do
     [...]
     set_property :min_prefix_len => 1
  end

-Calling the search function needs to specify the index or it will search across all indexes –

Library.search(keyword, { index => 'prefix_libary_index', <other params here> } )
