adapt fts base to odoo 8.0, change the following

1. fts_base\_openerp_.py

change from update_xml to data :  'data': ["fts_proxy.xml", 'wizard/fts_config.xml'],

2. fts_base\fts_base.py

change line 40 from cr = self.pool.db.cursor() to

      cr = self.pool.cursor()  # there is no db attribute anymore,

3. fts_base\fts_base.py and fts_base\fts_proxy.py

change from to_tsquery to plainto_tsquery if searching by key words separated by space other than by adding & bebween key words, e.g search by "full text search" other than "full & text & search"

extend website_forum module to enable full text search

here the highlight of the changes needed

1. install fts_mail

2. create new module fts_forum

  2.1 activate full text search on forum_post model by inherit from fts_base and specify the content field as full text search field

 2.2 extend the search function of forum_post class, adapt the search function from fts_base to search against the forum_post table directly and return the post ID. small tips 1.) there is parent_id = blank in args which means the result will bypass the answers , 2.) the comment stored in mail_message table other than in the forum_post table.
