hi anurag! a couple things are going on here. first, you actually do
need another index. appengine.ext.search converts search queries into
normal queries, with one filter for each search keyword. so, this:
User.all().search('hug bos').order('-date_joined')
is equivalent to this:
User.gql("WHERE __searchable_text_index = 'hug' AND
__searchable_text_index = 'bos' ORDER BY date_joined DESC")
so, you need a different index for each different number of search
keywords that you want to support. specifically, for this search
query, you'd need:
- kind: User
properties:
- name: __searchable_text_index
- name: __searchable_text_index
- name: date_joined
direction: desc
if you drop the sort order, you no longer need an index because the
query then has only equals filters. see:
http://code.google.com/appengine/docs/datastore/queriesandindexes.html#Defining_Indexes_With_index_yaml
the second thing, which is causing your confusion, is that the "bo"
keyword is being ignored due to this constant in appengine/ext/search/
__init__.py:
# words shorter than this will not be indexed. search keywords
shorter than
# this will be ignored.
_FULL_TEXT_MIN_LENGTH = 3
if you want to index and search on keywords under 3 characters, you
can change this constant by adding this code to your main(), or
somewhere similar:
google.appengine.ext.search._FULL_TEXT_MIN_LENGTH = 1
