### What is this PR for? As more and more document pages are added, it's really hard to find specific pages. So I added searching feature to Zeppelin documentation site([jekyll](https://jekyllrb.com/) based site) using [lunr.js](http://lunrjs.com/). - **How does it work?** I created [`search_data.json`](6e02423f54/docs/search_data.json) which is used for docs info template. `lunr.js` combines all of the text from all of the docs in `docs/` into `_site/search_data.json`. It looks like below.  All the info are comes from [Jekyll YAML front matter](https://jekyllrb.com/docs/frontmatter/) variables. (i.e. title, group, description.. that's why I rewrote all docs' title and description.) [search.js](6e02423f54/docs/assets/themes/zeppelin/js/search.js) will do this job using this data! ### What type of PR is it? Improvement & Feature ### Todos * [x] - Keep consistency for all docs pages' `Title` * [x] - Add some overview sentences to all docs pages' `Description` section (this will be used as the result preview) * [x] - Add apache license header to all docs page (some pages are missing the license header currently) * [x] - Add LICENSE for `lunr.min.js` ### What is the Jira issue? [ZEPPELIN-1219](https://issues.apache.org/jira/browse/ZEPPELIN-1219) ### How should this be tested? 1. Apply this patch and build `ZEPPELIN_HOME/docs` dir -> please see [docs/README.md#build-documentation](https://github.com/apache/zeppelin/tree/master/docs#build-documentation) 2. Click `search` icon in navbar and go to `search.html` page 3. Type anything you want to search in the search bar (i.e. type `python`, `spark`, `dynamic` ... ) ### Screenshots (if appropriate)   ### Questions: * Does the licenses files need update? Yes, for `lunr.min.js` * Is there breaking changes for older versions? no * Does this needs documentation? no Author: AhyoungRyu <fbdkdud93@hanmail.net> Closes #1266 from AhyoungRyu/ZEPPELIN-1219 and squashes the following commits:7ec8854[AhyoungRyu] Modify 'no result' sentence91b71a7[AhyoungRyu] Remove Apache license header since JSON doesn't allow comment34afd5d[AhyoungRyu] Add Apache license header to search_data.json6784282[AhyoungRyu] Minor search page UI update0389d28[AhyoungRyu] Make index.md not to be searched9f1ba42[AhyoungRyu] Disable enterkey press & change iconbd4956a[AhyoungRyu] Add docs.js & search.js to exclude list in pom.xml624b051[AhyoungRyu] Add Apache license header to search.js1381152[AhyoungRyu] Fix search result skipping issue6e775f5[AhyoungRyu] Make pleasecontribute.md not to be searchedee11136[AhyoungRyu] Fix some typosfa01299[AhyoungRyu] Refine 'description' in some docs as @bzz suggestedda0cff9[AhyoungRyu] Exclude lunr.min.js36ba7f1[AhyoungRyu] Add lunr.min.js license infof6a05a6[AhyoungRyu] Apply css style for the search results68eb997[AhyoungRyu] Attach 'Apache Zeppelin ZEPPELIN_VERSION Documentation: ' to titled908c37[AhyoungRyu] Add searching pagea951fa6[AhyoungRyu] Add search icon to navbar0688a79[AhyoungRyu] Keep consistency all docs' front matter for the right search result040f532[AhyoungRyu] Add template for storing docs info based on jekyll front matter0705bd6[AhyoungRyu] Add js files: lunr.min.js & search.js
