Search Fields

The search fields define what is to be searched. Using search fields, the user can focus their search to different text fields, limit the search to specific classification areas, and define specific date ranges for the search query.

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 specified by the user and written on the left-hand side of the query.

Search fields of the same type can be combined together using forward slash ( / ).
