NOW A REVIEW OF HAYSTACK

FINDING NEEDLE IN HAYSTACK

Haystack is a search api for django, it support several backend, including solr, whoosh,

A LITTLE SETUP(AGAIN)

Let do a little setup

git clone http://github.com/toastdriven/django-haystack.git

**show changes in settings.pyhttp://gist.github.com/376659

**show search_indexhttp://gist.github.com/376662

TELL HAYSTACK WHICH NEEDLE

We create a search index

** show search indexhttp://gist.github.com/376668

** search document place on <template dir>/search/indexes/issue/issue_text.txthttp://gist.github.com/376672

NOW TELL SOLR

Create solr index, and run index

create a schema.xml for solrpython manage.py build_solr_schema > schema.xml

create search indexpython manage.py rebuild_index

NOW CREATE A SEARCH SITE

We just reuse the search view** show urls.pyadd (r'^search/',include("haystack.urls"))

and create a template** show search/search.htmlhttp://gist.github.com/376685

VOILA!!!

Now we have a basic search.

except haystack can do quite a lot, which is another story altogether
