Search UI Changes

[kmcginnes]

These feature requests will require changing up the search UI.

I would suggest considering them as a whole and coming up with a search UI that will be flexible enough to allow for all these changes and any future changes we decide to make.

• [Feature Request] Allow for more than 10 search result vertices in search bar #106
• [Feature request] Attribute search should be case-insensitive #89
• [Feature Request] Boolean/greater-than/less-than search #70
• [Feature Request] Allow searching RDF database with URI #262
• [Feature Request] Unable to search for nodes by property if the property is datetime #105
• Named Graph support for RDF graphs #62
