RSolr::Error::Http - 400 Bad Request Error: ERROR:unknown field 'tags_ac'

Hello everyone !!
i did what's written :
but when i try to reindex.. i have this error :
rake aborted!
RSolr::Error::Http - 400 Bad Request
Error: ERROR:unknown field 'tags_ac'

as the model that searchable called Experience and i put this block in it

searchable do
text :tags, :boost => 3
text :title, :boost => 2
text :tips
autocomplete :tags, :using => :tags
end
what's the problem guys ? Thanks a lot :)

I think the problem should be in the declaration
autocomplete :tags, :using => :tags

that should be changed in this way:
autocomplete :classname_tags, :using => :tags

for example, the configuration for my Account class is:

class Account
  include Sunspot::Mongoid
  searchable do
    autocomplete :account_username, :using => :username

    text :username
    text :first_name
    text :last_name
  end
end

yes it worked now Thanks a lot .. but i have another problem ..in the last step i put in the view file

<%= autocomplete_text_field "experience", "tags", "http://127.0.0.1:8983/solr/", "experience_tags"%>

it appears in the browser like this :

<script>$('#experience_tags').autocomplete('http://127.0.0.1:8983/solr/', 'experience_tags', {});</script>
and not a text box !!

i want the autocomplete text box and also i want to put it in a form which will pass the query to the controller ..
just like this :

<%= form_tag experiences_path, :method => :get do %>

<%= text_field_tag :search, params[:search] %> // the autocomplete box should replace this

<%= submit_tag "Search", :name => nil %>

<% end %>

Thanks a lot man for your help :)

Hi.

I think you are missin the raw helper.

<%= raw autocomplete_text_field

TL;DR: Solr seems to crash because of some corrupt contents in the solr/data folder. So delete it, stop solr, start it again, and reindex to create the solr/data folder again.

What worked for me was deleting the solr/ folder, and then starting solr again so that it would generate that folder again. I then replaced the solr/conf folder with my backed up version. Git status says that nothing has changed, so I presume the change that actually did the trick was the newly generated solr/data folder (which is in my .gitignore).
