Hi guys, Since there is no full-text search available in GAE/j and I really need this for a new app I am writing I have made a prototype implementation of an inverted index using GAE store.
Term is stored as a key with actual term as name in key (only key is needed) Below each term I've added document references as another key like this Term("term")/DocumentRef("10") where 10 is the internal document number. An example: Term("stuff") DocRef("1") DocRef("2") Term("more") DocRef("1") When searching for e.g. "more stuff" (which is boolean and) I do this: Query DocRef's from the Term with the least doc-refs (children, this info is cached) and load keys into a sorted set. Then query for doc-refs under the second term filtering from the min. doc-id in the sorted set and the max doc-id (meaning we only get possible matches in the docs we've know contains the first term. Merge sets. What do you think? Is this a fair way to implement this (working on scoring using tf-idf) and do you think its possible to get it to perform well? /Lars Borup -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
