Django interface to postgresql's full-text search functionality
License: Other
django-fts-odeon is a fork of django-fts ( http://code.google.com/p/django-fts/ ) The only supported back-end is PostgreSQL Dependencies: - Django - PostgreSQL Install: - add "FTS_BACKEND = 'pgsql://' " in settings.py and "fts" to INSTALLED_APPS - ./manage.py migrate fts Usage: - subclass your model from fts.SearchableModel - create a custom manager with the list of fields that should be indexed (CharField and TextField only) class Blog(fts.SearchableModel): title = models.CharField(max_length=100) body = models.TextField() search_objects = fts.SearchManager(fields=('title', 'body')) # index both fields - create FTS indices with ./manage.py create_fts_indices - if you need to update by hand all the search indices for some reason, you can do "./manage.py update_fts_indices". Normally, the indices are always up to date because postgres takes care of them on each insert/update/delete. - getting the results ordered by rank in postgres (the rank field's name is not important. Just avoid any clashes with existing fields): Blog.search_objects.search('foo bar', rank_field='rank') - highlighting results (highlight_field is the actual model field where you want the highlighting done. The modified text will be placed in a new field called highlight_field+'_highlight'): for blog in Blog.search_objects.search('foo bar', highlight_field='body'): print blog.body_highlight - see fts_test/tests.py for more examples website: http://od-eon.com/labs/django-fts-odeon/ contact: [email protected]
