What does has in thinking_sphinx attributes do? - sphinx

Can someone here elaborate on what actually does 'has' do in the attributes section of thinking_sphinx? I have gone through the documentation at Thinking sphinx. But, couldn't get what actually it does.
Please help me in this issue.

The source code has an explanation. Scroll to line 112.

Expand-all for Confluence UI-Expand macro

I've poked around Google and the Atlassian forums about this, and have not found an answer to this anywhere.
I'm trying to come up with an "Expand All" button for the UI Expand (important: not the regular Expand) macro.
I found this link in the Atlassian forum. I've been messing around with it, but I haven't been able to get it to work in my Confluence pages. I suspect that part of the problem is the UI Expand naming convention -- the link, which assumes the regular Expand macro, uses ".expand-control", but I'm wondering if it needs to be something like ui-expand, ui-expand-control, RWUI, etc. I've tried different combinations, and haven't gotten it to work.
Has anyone else come across this? Has anyone figured this out?
Thanks in advance...
I figured it out! The correct class name is rwui_expand.
I took the code from the Atlassian forum and changed it from this:
jQuery(".expand-control").each(function(){ jQuery(this).trigger("click");})
to this...
jQuery(".rwui_expand").each(function(){ jQuery(this).trigger("click");})
Works like a champ!

Django-CMS page admin interface style jstree broken

Here's how my interface looks:
I tried fiddling with the CSS but I guess there's something I'm missing and this is broken.
Here's the code for the page.
Any clues, please?
If this is something obvious- great. Else, I'll dig in and provide more details but I have a hunch that this may be something obvious to someone smarter than me.

adding Contact/Number into Textview/textfield like default MessageComposer did

As like my other questions I tried to search for this. But I didn't get anything.
Maybe my path is wrong. Please direct me.
Here is my Question : I have a UITextView. In that I am going to add Numbers, Names and contacts.
I want to show each number separately as MessageComPoser did.
Does anybody know how to make this?
If my question is not worthy, give me the correct answer then downvote.
(For my questions somebody downvoted without even giving any answer!!)
There is no way to do this using apple's native framework, they didn't provided any controls for doing the same.
You can use the TTMssageRecipientField provided by Three20 framework.
I found the Answer. I don't want to use Three20 library since it is Very difficult to use in my project.
