Thanks @lresende for contribution.
I have tested this patch, but i still get the same error.
How to test
1) build `gh-pages` (website) branch
```
bundle exec jekyll build --safe
mv _site /tmp/zeppelin_website
```
2) build this patch (docs) and copy it under docs/0.7.0-SNAPSHOT of website
```
cd docs
bundle exec jekyll build --safe
mkdir /tmp/zeppelin-website/docs
mv _site /tmp/zeppelin_website/0.7.0-SNAPSHOT
```
3) start httpserver
```
cd /tmp/zeppelin_website
python -m SimpleHTTPServer
```
And browse localhost:8000, select 0.7.0-SNAPSHOT doc and try search
