Allow for search by any node attribute (instead of just node label)

You guys really doing a great job, it will be really nice if you guys can make the search working on the attribute as well, it will save us a lot of extra search function

I'm glad you're finding the code useful. Take a look at this comment for a way to enable the attribute search. This is something I definitely want to add in the main package as soon as my schedule allows.

Thanks a lot for the help, we currently load 47K+ node, and 96K+ edges, and we already applied that change, and it works very smooth after it finish load up.
Another question is that is there a way to prevent download directly on the json file, since we'd more like people to use it through the GUI instead of taking the raw data
