I'm a front-end developer, so I put all front-end skills I know into search with OR operator. Then, there are much more skills that I don't know, so I put all of them into search with NOT operator. Or at least that's what I used to do before latest job search "update". Now I run out of character limit halfway between endless PHP frameworks and ecommerce solutions.
Anyone else find it to be a problem? Or maybe there are a lot of people who like the limit and had their user experience improved by it?
