Full-text search using Google App Engine and JDO?

Question

I am using Google App Engine (Java) with JDO. How can I do the equivalent of JDO

select * from table where field like '%foo%'

The only recommendation I've seen so far is to use Lucene. I am a little surprised that some of this basic is not possible in the finished GAE.

Answer 1

App Engine. , App Engine , . , "". , , , - , .

, , , Lucene. Lucene on App Engine, GAELucene. , .

Answer 2

tl; dr: .

: , - , :

• searchTerms. , .

• , , . . , . . , . , .

• , ( ) equals searchTerms.

  ( = , - .)

  ( Objectify):

  Query query = dao.ofy().query(Recipe.class);
  for (String term : search.toLowerCase().split(" ")) {
    query = query.filter("searchTerms =", term);
  }
