Hello,
I have been trying to run a search through ts and have been running up
against a very vexing error.
We have a documents table, where each document has a certain number of
pages belonging to it. We want to search and return results from the
documents table, but we want to index the text of all the pages
belonging to the document.
Here is the define_index code in our Document model:
has_many :pages,
:order => 'page_number ASC'
define_index do
indexes pages.text, :as => :doc_text
has app_id, :as => :app_id
where "status = 4"
end
And here is where we make the search() call:
word_matched_docs = Document.search("*#{word}*", :per_page =>
1000, :max_matches => 1048576, :with => {:app_id => self.id})
Every time I make this call, I am getting the following stack trace
out of the plugin:
Fatal error sent to user during search: NoMethodError -- You have a
nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.last

Something seems to definitely be wrong within Thinking Sphinx itself
and not the sphinx index because if I run the "search" command through
the command line I get the results I expect:
search -f app_id 12 -c /current/web/config/qa.sphinx.conf business -l
10
We're using version 0.9.8.1 of sphinx and Thinking Sphinx 1.3.17 (a
commit or so after) installed as a plugin.
Can anyone tell me what I might be doing wrong? Is it something to do
with the association between the Document and Page models?
Thanks for any assistance.
Greg
