Currently there is a bug with the Main Search field that is located in the Navigation bar of Nexa. If you use the main search (located in the upper right hand corner of Nexa), it will return an Unspecified network error. 

Until the bug can be addressed, please use the column searches in the individual indexes. 

Example: to search for a company, click on the 'Companies' menu in the Navigation bar and select 'View Companies' 

Then type the name of the company you are looking for in the search bar at the top of the 'Company Name' column in the index.
