Search In a Specific Source

Note: The information in this topic applies to Lexis® URL API users. This application programming interface (API) lets users execute tasks in Lexis® using URLs, rather than the standard user interface. Please contact your LexisNexis representative if you would like additional information about this feature.

Use the source parameter to search in a specific source. You can use multiple sources, separated by a period. If you don't specify a source, all sources are searched.

Contact your LexisNexis® account representative to find out the value for the sources you want to search.

The source parameter is optional. It is shown below in a URL using search terms.
