Improvements to search functionality

[ksatchit]

https://github.com/algolia/docsearch-configs/blob/master/configs/litmuschaos.json has the default style configs. In case, some customizations are required - we need to send a PR to this file.

https://docsearch.algolia.com/docs/styling/ has the styling guide - not hands on with CSS, so did not touch defaults :) but welcome to improve on it and send PR to above file.
