Search Fields
Search fields can be defined using the Fielded search interface and via search commands in the Command Line.
There are 6 different types of search fields, each containing different types of content. The 6 types of search fields are:
- Text Fields
- Number Fields
- Date Fields
- Country & Kind Codes Fields
- Classification Fields
- Party Fields
- Legal Status Fields
When using the command line, search fields are written on the left-hand side of the query.
Search fields of the same type can be combined together using forward slash ( / ).
