Haystack Whoosh not indexing everything

I am using Haystack v1.0 and Whoosh v1.8.1 to build a customized search engine for my website. Everything works beautifully but the problem is that I get no results for a lot of entries in my indexed models.

For e.g. - I have four registered models - Member, Guest, Event, Sponsor. On rebuilding index from django shell, following happens:

./manage.py rebuild_index

Indexing 26 members.  
Indexing 3 events.
Indexing <x> guests.  
Indexing <y> sponsors.  

But on running the SearchQuery API commands and also on searching through the search page, I cannot 开发者_如何学编程search half the member names. What eludes me is that when I can search 14-15 members, why not the rest. My template *_text.txt* file should be correct since half the members are getting indexed correctly.

You can try this

x= Vikesh returns 1 result (as expected)

x= Akshit returns no results (the problem!)

Both values 'Akshit' and 'Vikesh' were present prior to rebuild_index. Here's the list of all 26 members that I am trying to search - http://www.edciitr.com/contact/

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 = open_dir('/home/somedir/my_project/haystack/whoosh/')  
$>> ix.schema  
<Schema: ['branch', 'category', 'coordinator', 'date_event', 'designation','details', 'django_ct', 'django_id'> 'name', 'organisation', 'overview','text', 'title']>
$>> searcher = ix.searcher()  
$>> res = searcher.search(Term('text',u'akshit'))  
$>> print res  
<Top 1 Results for Term('text', 'akshit') runtime=0.000741004943848>
$>> print res['0']['name']  
u'Akshit Khurana'   

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='akshit')
 $>> 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

'''Uncomment 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 but I would like to know what's the issue with haystack here.

I have a similar symptom, and this is the question I asked Django django-haystack cannot import CategoryBase from django-categories on the first run

Might relate to your problem too.
