Error - Sharing the Same URL for two different views in exposed filter
You can use Views Glossary to create a glossary that is grouped alphabetically, and then add an exposed filter to search by Keyword.

Enabling the module provides you with an example view that you can clone and modify to get the functionality you need.


Clone the view "Views Glossary Example" to create your /glossary view
Add your exposed filter for your keyword search.
Open contextual filters and change the Title filter to "Display all results for the specified field" when the filter value is not in the URL. If you don't do this, the view will only display results for 'A' when no letter is selected.


This will allow users to simultaneously search the glossary using keywords and/or filter the glossary alphabetically.
