Discovery: Search doesn't work on Dynamic Content if the

So, this may be a bug or an undocumented feature but I felt like I should share my discovery. I've been having getting search to work for my custom modules. I discovered today that the culprit was a field by the name of "Category". Removing this field allowed search to work. Renaming also worked. To confirm, I made a new test module without the field and search worked. Upon adding a "Category" field, search was broken. 

Have fun with this one guys! :)

Yes, me too faced the same issue when we have a field name category in content type. Now its in production and we cannot change it.

Got the following error
