Just for future reference, here was the answer (posted here as well
http://stackoverflow.com/questions/1972107/thinking-sphinx-not-recognizing-setproperty-minprefixlen):
-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> } )
