Re: [xwiki-devs] Re(2): HQL queries to select tag

Thank you so much so far I tagged three pages with this set of tags 1.º page: PRINT|KB-4D 2.º page: ARQUIVO|KB-FRAMEWORK 3.º page: PERSISTENCE|KB-FRAMEWORK|KB-4D After run the query you wrote I get the expected result: - KB-4D - KB-FRAMEWORK - PERSISTENCE - PRINT I tried to integrate a criteria expression "not like 'KB-%' in the query to filter the first two tags (KB-4D, KB-FRAMEWORK) useless for the final porpose (select all the subjects of a knowledge base) but without sucess. Can you help me in this? The main reason that keeps me far from my objective is not understand the mapping of XWiki database or how it's implemented. Can you give some information or documents you already have?
