Hi, With App Engine, there is not a great way to do partial string searches. To do prefix matching, which seems to be your use case, you can use inequality filters and the method described here: http://code.google.com/appengine/docs/datastore/queriesandindexes.html
"Query filters do not have an explicit way to match just part of a string value, but you can fake a prefix match using inequality filters: db.GqlQuery("SELECT * FROM MyModel WHERE prop >= :1 AND prop < :2", "abc", u"abc" + u"\ufffd") This matches every MyModel entity with a string property prop that begins with the characters abc. The unicode string u"\ufffd" represents the largest possible Unicode character. When the property values are sorted in an index, the values that fall in this range are all of the values that begin with the given prefix." -Marzia On Tue, Jan 6, 2009 at 12:59 AM, chromerunner <gau...@gmail.com> wrote: > > A noob question.
