I executed a GQL query to test for some results in Datastore viewer: SELECT * FROM DbLaw where keyWordsList='leg' and keyWordsList='24' it worked OK.
The same query using JDO: Query text: SELECT FROM biz.ebas.server.DbTest WHERE keyWordsList=='leg' && keyWordsList=='24' Threw this exception: "The built-in indices are not efficient enough for this query and your data. Please add a composite index for this query.. An index is missing but we are unable to tell you which one due to a bug in the App Engine SDK. If your query only contains equality filters you most likely need a composite index on all the properties referenced in those filters." How can this be possible ??? Low-level speaking, aren't the same Queries ? the same datastores ?
