Similar documents

Similar documents (also known as near duplicates) are documents that share nearly all of the same text. They are documents that have 80% or more the same content, but may not be exactly the same. The similar documents feature in DISCO allows you to adjust this similarity percentage to give you greater control over the documents you are working with. 

Searching similar documents

To find similar documents in your database, add the search syntax similarcount(X to XXX) into your search string, replacing the Xs with a number or numbers. For example, you could search similarcount(>2) to find all documents with more than 2 similar documents.

Viewing similar documents

There are two ways to view similar documents within DISCO. First, from your search results screen you will see an icon on the left side of the result row that indicates there are one or more similar documents associated with this document.

The second way is in the document viewer. Click a document in your search results that has similar documents. In the viewer, you can navigate between the similar documents and view their details in the RELATED DOCUMENTS section.

Adjusting similarity

You can also adjust the percentage similarity of the documents you are viewing.

The similarity percentage dropdown shows the number of documents that are included within the specified percentage of similarity. In addition, the Exact hash match count displays the number of documents that are exact matches (that is, they have the same hash). By default, these exact duplicate documents and/or overflow documents are included in the similar documents listed. If you do not want to include these documents, clear the Include exact duplicates checkbox.
