Is there a way to get Chrome to use a %20 instead of a + sign for spaces when using keyword search?
Solution 1:
I never found a way to do this, so I ended up writing an open source extension for Chrome. I'll warn you, it is hard coded to the https://privatewebsite.com/, so you won't be able to Ctrl+C, Ctrl+V it for your needs, but it is available under the MIT license for you to use as necessary.
I think the most important aspect of what I did was to use the encodeURIComponent(searchText) javascript function to get the %20's I needed.
