Live Search Macro and Include Page Macro not finding pages in editor 4

When we have pages that start off with a part number in the title. So the title might be something like: LD-F4SW7Y

When using LiveSearch Macro or the Include Page Macro I start off by typing: "LD-"

At this point, the dropdown will show the results, but if I type another letter such as: "LD-F" it says that nothing is found. For some reason anything after the '-' is causing the search not to find results.

Tested in 3.4.x and 3.5.x and the same behavior occurs. In Firefox, IE and Chrome.
