Django Haystack Indexing More than one models

I am trying to implement Haystack search for my website with Whoosh back-end. I have been able to successfully setup the haystack app and I can search the model that I have registered, but when I create the search_indexes.py file for another app, I am having the following issue:

I have two models: Member and Events. I create a search_indexes.py for both of them and the corresponding /search/... _text.txt files in the template folder. Then I use ./manage.py rebuild_index

I get the following message:

Indexing 8 events  
Indexing 5 members

However, I am not able to see 13 indexed items:

 $> ./manage.py shell    
 $> from haystack.query import SearchQuerySet   
 $> sqs = SearchQuerySet().all()  
 $> print sqs.count()  
 $> 8

And these are the 8 events that were indexed. Consequently, from the website, I can only search the events, not the members. Deleting the search_indexes.py file from the 'Event' app folder and redoing everything indexes the 5 members correctly and they can be searched as usual. What could be the reason for this?

Update: I included the search_indexes.py files in others apps also to see whether they are indexed properly. I get the following message on rebuilding the index:

Indexing 8 events.  
Indexing 4 guests.     
Indexing 5 members.    
Indexing 8 sponsors.    

Now, it is indexing all the events and members but none of the guests and sponsor. I am able to search for events and members but not for the other two (using both the SearchQuery API and the web开发者_开发问答site)

Update: Issue seems to have been resolved by changing the source of haystack.backends.whoosh_backend. Please see the answers

I've had the same problem the past couple of days (nice timing). I decided to start where you left off and see if I couldn't isolate the cause a bit better.

The narrowed results are (at least partially) generated by a query of the models which are registered to the site (L298 and on). For my code, the query it generates is...

django_ct:(barnaby.tag OR barnaby.userprofile)

...which gives a resultset with only barnaby.tag models. However, if I run...

django_ct:(barnaby.tag OR barnaby.userprofile) (username:pfrazee OR name:Tag114)

...I end up getting results from both tag and userprofile. I can only assume that's a problem with Whoosh, but I can't say for sure. We should probably contact Haystack and/or Whoosh about it.

At any rate, you can avoid this problem without altering haystack by setting this:

HAYSTACK_LIMIT_TO_REGISTERED_MODELS = False

Okay, so here's what I did to find out whether the problem is in Whoosh or Haystack. I opened the django shell and performed a search for the term that was not showing up in haystack SearchQuery API search:

./manage.py shell   
$>> import whoosh 
$>> from whoosh.query import *  
$>> from whoosh.index import open_dir  
$>> ix.schema  
<Schema: ['branch', 'category', 'coordinator', 'date_event', 'designation','details', 'django_ct', 'django_id'> 'name', 'organisation', 'overview','text', 'title']>
$>> ix = open_dir('/home/somedir/my_project/haystack/whoosh/')  
$>> searcher = ix.searcher()  
$>> res = ix.search(Term('text',u'pink'))  
$>> print res  
<Top 1 Results for Term('text', 'pink') runtime=0.000741004943848>
$>> print res['0']['name']  
u'Pink Floyd'   

So you see, Whoosh is correctly indexing all data. So, now I try the SearchQuery API

./manage.py shell
 $>> from haystack.query import SearchQuerySet
 $>> sqs = SearchQuerySet().filter(content='pink')
 $>> sqs
 $>> []

So, I realize that I must check out the whoosh_backend.py file of the haystack library to see what's happening. Open - haystack.backends.whoosh_backend around line number 345

'''Comment these two lines because the raw_results set becomes empty after the filter     call for some queries'''
if narrowed_results:
      raw_results.filter(narrowed_results)

to

#if narrowed_results:
      #raw_results.filter(narrowed_results)

And then it works. SearchQueryAPI returning exactly one result for the test query as expected. Web search working. Time for sweet sleep, though I would like to know what's the issue with haystack here.
