Overcoming the size entry size limit for appengine search?

I am trying to use a searchable model for blog entries and it worked fine on the development platform but when I try to add an entry in the cloud I get an error:

Traceback (most recent call last):
File "/base/python_runtime/python_lib/versions/1/google/appengine/ext/webapp/init.py", line 517, in call

it over the limit: entity_type: "Article",ancestor: false,
Property { name: "searchable_text_index", direction: ASCENDING},
Property { name: "searchable_text_index", direction: ASCENDING},
Property { name: "date", direction: ASCENDING}

These entries aren't that large(<500 words) is the limit that low? The only way I can think to get around this is to store the entry as a non-searchable model and also break the entry text up into smaller searchable models, that each reference the main entry. Any help is greatly appreciated

What you seem to be running into are called Exploding Indexes. You can read more about them here: http://code.google.com/appengine/docs/python/datastore/queries.html#Big_Entities_and_Exploding_Indexes

Basically you can't use AppEngine to create a full-text engine, unless you have a very small dataset. It's either you'll run into exploding indexes or you'll run into other issues (i.e. merge join timeouts). I recommend that you look into a service called IndexTank which is a very good full-text search service. It has a full REST api and python client so it's easy to get going on AppEngine.
