I found that if there is no input for lucene query, no results will be returned. But In link suggestion, when user first type "[[", there is no queries, so no suggestions will be got, but Marius and I excepted there is a default suggestion results for users, like the recent modified pages, and the attachments belong to the current edited pages if exists.
Marius give me wiki page: Panels.Recently Modified, there is an page object for getting the Recently Modeified pages. I have tried to enhance this object so that it can return json results which can be used as a web service, so I edit the content of the object of this page, the code is below: {{velocity}} *#set($media = "$!request.media")* #set ($recentlyModified = $xwiki.searchDocuments('where 1=1 order by doc.date desc', 5, 0)) #if ($recentlyModified.size()> 0 || $showEmptyPanels) *#if($media == 'json') $response.setContentType("application/json") {'test':'mytest'}* #else #panelheader($msg.get('panels.recentlyModified.title')) #foreach ($docname in $recentlyModified) #if ($xwiki.hasAccessLevel('view', $xcontext.getUser(), $docname)) #set ($rdoc = $xwiki.getDocument($docname).getTranslatedDocument()) #if ($foreach.index> 0) (% class="pitemseparator" %) ~| (%%)## #end (% class="panelitem" %)[[$rdoc.plainTitle>>$rdoc]](%%)## #end #end #end #panelfooter() #end {{/velocity}}
as you can see, I add an parameter named "media", if the media is json, then return the json file, otherwise the default behaviour will be executed. I tested the code above, and the json result is not "*{'test':'mytest'}*", but contains some other html tags.
Can anyone tell me why?
James, you have to call the page like you did with your initial fake link suggestion service and with the XWiki.SuggestLuceneService page: ?xpage=plain&outputSyntax=plain
Yes, I have tried the url: http://localhost:8080/xwiki/bin/get/Panels/Recently+Modified?xpage=plain&out... but still can't get the right result.
Hope this helps, Marius

Hi All, how can I query the attachments of a specific page, for example "Main.testpage"
I found if I use the query space:Main AND filename:__INPUT__* AND type:attachment I can get the attachments only from the Main space.
but how about a specific page, I have tried page:Main.testpage AND filename:__INPUT__* AND type:attachment wikipage:Main.testpage AND filename:__INPUT__* AND type:attachment but no one can give the right results.
To see which fields are indexed, you can look at the Java sources, starting from
https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwik...
The document name is indexed both as "name", which holds just the name, without the space, and "fullname", which contains the space as well -- Space.Document

Hi James,
That's just a query problem. The queries that are used for the search suggest are located in XWiki.SearchSuggestConfig. The query for
Document
Name/Content are not complete. They also need to specify that the result should be a document, and not anything (like attachments for instance). The correct query for searching for documents by document name should be:
name:__INPUT__* AND type:wikipage
For attachment name, the correct query should be:
filename:__INPUT__* AND type:attachment
So, for your usecase (quering documents by name or attachments by name), the query should be:
(filename:__INPUT__* AND type:attachment) OR (name:__INPUT__* AND type:wikipage)
I`ve tested it out by creating a page named "IconTest" and then searching for "icon". The results were:
<results> <rs id="/xwiki/bin/download/XWiki/RequestsStatus/icon.png" info="XWiki.RequestsStatus">icon.png</rs> <rs id="/xwiki/bin/download/XWiki/ExtensionManager/icon.png" info="XWiki.ExtensionManager">icon.png</rs> <rs id="/xwiki/bin/download/Panels/PanelWizard/icon.png" info="Panels.PanelWizard">icon.png</rs> <rs id="/xwiki/bin/download/XWiki/OfficeImporterAdmin/icon.png" info="XWiki.OfficeImporterAdmin">icon.png</rs> <rs id="/xwiki/bin/download/XWiki/SearchAdmin/icon.png" info="XWiki.SearchAdmin">icon.png</rs> <rs id="/xwiki/bin/download/Blog/Categories/icon.png" info="Blog.Categories">icon.png</rs> <----------- attachments <rs id="/xwiki/bin/view/Main/IconTest" info="Main.IconTest">IconTest</rs> <----------- documents </results>
Ignore the fact that the result is in XML, you can make it json, as suggested in my previous mail.
Hope that works for you.
Thanks, Eduard

Thanks Eduard very much, It is really helpful, today I am trying to use SuggestLuceneService to test the autosuggestion functions, I found a problem.
For example, I create a page named "jamesxu", and upload an attachment named "autosuggest1.js", then I input the query "jame" to the search box on the top right of the page, the suggestion list shows up, but the results in the "Document Name" and "Document Content" contains both the wiki page "jamesxu" and its attachment "autosuggest1.js", this behaviour is not excepted in the autosuggestion features of the editor, because when user types "jame“， he really wants to query the wiki page or attachment begin with or contains "jame", the attachment "autosuggest1.js" does not contains "jame", it should not be included in the suggestion results.
