I have been trying to get xapian working django haystack for a project im working on that requires some search functionality but have run into a bit of a wall!! Basically i got everything installed per the instructions, so:
ran make install for xapian-core and the xapian bindings ran pip install haystack and pip install xapian-haystack and everything installed correctly
As im using the django cms app i simply copied thier example over to give the search functionality a test and ran into this error
InvalidIndexError at /search/
Unable to open index at /home/mike/sites/xapian_search
I have tried several different paths for the HAYSTACK_XAPIAN_PATH setting and have also encountered another error
OSError at /
(13, 'Permission denied')
the folder xapain_search has been given full perms (chmod 777) and theres an xapian_index.php file with full perms too. Im not sure what im missing here but im desperate to try and get this working!!
my haystack settings look like
HAYSTACK_SITECONF = 'lactoseintolerant.lactose_search'
HAYSTACK_SEARCH_ENGINE = 'xapian'
HAYSTACK_XAPIAN_PATH = '/home/mike/sites/xapian_search'
HAYSTACK_SEARCH_RESULTS_PER_PAGE = 50
Any advice would be greatly appreciated!!
edit
Hey again i think this error is relating to the fact that there are no indexes(is that right?) i have run the commands update_index rebuild_index clear_index all of which dont seem to do anything, there are no errors outputted but still the indexs never seem to be built when the commands are run
i have an app called lactose_search which my HAYSTACK_SITECONF points to like so projectname.lactose_search in this app folder i have a file called search_indexs.py. For now i have simply c+p the example from the django cms site as it is the cms_app content i want to search this file looks like

Hope this extra info may make answering this question abit easier!
