android - In GreenDao, build a join query with OR instead of AND -


i generated sqlite db greendao v2.1.0. here diagram (a tiny piece of it)

a contact can have many phone numbers. want make search query : list contacts given_name or family_name or phone.number contains specific word.

for example, with these entries, if use word "bob" contact sponge bob returned. if use word "222", contact patrick star returned.

since, 2 tables involved in query, resorted join solution piece of code : 

    querybuilder<contact> qb = getcontactdao(context).querybuilder();     qb.whereor(contactdao.properties.given_name.like("%" + word + "%"),                contactdao.properties.family_name.like("%" + word + "%"));     qb.join(phone.class, phonedao.properties.contact_id)       .where(phonedao.properties.number.like("%" + word + "%"));     list<contact> contacts = qb.list();

this generates following sql : 

select t."_id", t."given_name", t."family_name" "contact" t   join phone j1  on t."_id"=j1."contact_id"  (t."given_name" ? or t."family_name" ?) , j1."number" ?     collate localized asc

the 5th line points out problem : "and" connector. desperately trying replace "or".

am missing ? shall leave join solution ? :)

i have same problem. seems greendao not able that. resorting using queryraw() instead.
