[fix #7986] Problem in searching with space using chosen

[gunjanpatel]

Steps to reproduce the issue

• Create a category having space in name. For example: "Events and Forms"
• Make sure you have more than 10 categories, if not try to copy it.
• Go to article create/edit page, In category selection try to search "event and "

• Now, close the article edit page and go to article listing page. Select any article and click on batch button from toolbar and try to search "event and " like below and notice it is working.

Expected result

It should looks like below in article edit page.

System information (as much as possible)

I have tested it in FF41.0 Ubuntu. But I believe it's not dependent on browser or OS.

About B/C, you are altering the default value who was false Here

[gunjanpatel]

I think it will not, because that is core option this.search_contains = this.options.search_contains || false; and I am setting default option for joomla to set search_contains to true.
I think it is okay to enable search_contains it won't harm any functionality. Instead of that it will fix the bug with search using space in all select boxes.
