If I want to get the doc's wiki name, how is the
query, I have tried
doc.wiki, and doc.wikiName, no one is right;
The above query is executed by default on the current wiki so all
documents will obviously have the same wiki name. You can specify the wiki:
$services.query.hql(yourHqlQuery).setWiki("foo").execute()
as indicated on the first link below, but you can't execute an HQL query
across multiple wikis because they use different schemas.
The reason you can't select the wiki name from the document in the query
is because the wiki name is not stored in the document table. It is of
course implied by the schema where the document table is.
I think Eduard mentioned before that REST search is limited to one wiki,
the reason being that is uses HQL queries. Lucene search on the other
hand allows you to search across wikis.
You have to know that there are cases (see myxwiki.org) when wikis have
different owners who don't want to share their information. In this case
it is not desirable to suggest wiki pages from wiki A to users of wiki B.
Suggesting only wiki pages and attachments from the current wiki is
enough for now.
Hope this helps,
Marius

You can add your code to the "Recently modified" panel for now, but
return the list of attachments only when a specific request parameter is
present.

(2) When user keeps typing, then he can trigger some sub link triggers
like "attach:", ".", "@" and "||"
If "attach:" is triggered without any
queries, should we give the user
some default suggestions, if so, what suggestions should we give, till
now, I give the the attachments start with "a" as default.
You need to propose something. We can help you make the choice but you
should be the one coming with great ideas.
if "." is triggered, there are two
situations: first is under the
wikipage context, so when it is triggered without any queries, what
should we give to user as default suggestions,
Again, you have to propose something.
because when "." is
trigger, we must narrow the search range to the specific space, for
example, when user type "[[Main.", then the suggestions and also the
default suggestions should under the Main space.
second is under attachment context, like "[[attach:Main.", what should
be the default suggestions for users?
Is there really a difference between "[[Main." and "[[attach:Main."
with
respect to the list of wiki pages that you could suggest?
if "@" is triggered, we must give the
attachment suggestions to users
under attachment context, like "[[attach:Main.mypage@", so what is the
default suggestions for this situation?
What do you propose?
if "||" is triggered, I think we may
not query the server, because the
attributes of link are static, but what attributes are supported?
First check the syntax help, then try some random parameters and check
what HTML is generated when the page is rendered.
Hope this helps,
Marius

find
the
right search queries of suggest lucene service to get right
suggestion results.
3. The autosuggestion can use the real datas from xwiki now.
In this week, I am going to do the following
things:
1. Implement the whole context for link suggestion, include
"attach:",

designations, but still want > discuss with mentors)
> 2. Consider to implement the ctrl+space to re-open the suggestion
box
according to the different contexts of link suggestion.(after the
1 is
finished)
Sounds good. Ping me on IRC when you need help.
Thanks,
Marius
