[server] prevent returning closed cursor to the database pool In since c8c6ad8 init_repository use repo.internal_cnx() instead of repo.system_source.get_connection() so it use the pool and we should not close cursors from the pool before returning it back. Otherwise we may have "connection already closed" error. This bug only trigger when connection-pool-size = 1. Since we are moving to use a dynamic pooler we need to get this fixed. This does not occur with sqlite since the connection wrapper instantiate new cursor everytime, but this occur with other databases.

You can as well type complex queries using the RQL_ query language,
used every where to build dynamic pages of this site.

You can use one of the following prefixes to specify which kind of search you
want:

* `rql` : RQL query
* `text` : full text search
