ogterran,
It should do one for the search and then one for each item in the search
result. If you are worried performance on the calls to the datastore you can
modify this code to make the ProductSearchIndex entity be a child of the
Product entity and use a key only query to retrieve only the keys for the
search index entities (since we only really care about the Products anyway).
This will still to the same number of queries but will avoid the overhead of
deserializing the ProductSearchIndex objects (and the associated index list
property which might be long).
Something like the following should work:
class Product(db.Model):
pid = db.StringProperty(required=True)
title = db.StringProperty(required=True)
site = db.StringProperty(required=True)
url = db.LinkProperty(required=True)
class ProductSearchIndex(search.SearchableModel):
# parent == Product
title = db.StringProperty(required=True)
...
# where you write the Product
product = Product(pid = pid, title=title, site=site, url=url)
product.put()
index = ProductSearchIndex(parent=product, title=title)
index.put()
...
# where you search
keys = ProductSearchIndex.all(keys_only=True).search(query).fetch(100)
for key in keys:
product = Product.get(key.parent())
print product.url
