More Like This
Insight includes More Like This, which provides the ability to find documents similar to the document you are reviewing.
Use your mouse to highlight specific content within the Text view of the record. The More Like This button becomes available above the body of the document at the right. The number of characters you have highlighted is also displayed (there is a 5,000 character maximum).
Clicking the More Like This button runs a BodyText search with an OR connector between each value within the text you highlighted. The Results page returned by the Search displays the query and the documents. You can remove or add new values or clauses to the search and use Folders and Advanced Settings to define other search parameters.
