Hit highlighting allows you to quickly locate important words or phrases in the document you are currently viewing. There are three types of hit highlights:
- Search Hits: Terms or phrases, if any, from the content search(es) used to retrieve the document. This can help guide you to relevant sections of the document.
- Custom Hits: Highlights that can be added by you as you review documents. These are useful for finding contingently important information in the document you are viewing.
- Persistent Hits: Highlights set up by project admins that will appear for all users in the project. These are useful for creating a standard set of important words or phrases across a project.
The hit highlighting panel displays all the different highlights found in the document, and can be found on the right side of the review window in the PDF, text, and native views of the document. If the image of the document is not a PDF with extractable text, the hit highlighting panel will only appear in the text file view. Note: hit highlighting for large text files will only show hits from the first 5MB. To locate content later in large documents, download the Text file and search through it offline.
Hits may appear on any page of the document you are viewing, and you may be taken to different pages of the document as you navigate through the hits. Here are the different sections of the hit highlighting panel:
The first section of the hit highlighting panel shows you how many total hit highlights are present in your document - across search hits, custom hits, and persistent hits. You can navigate through the hits by using the arrow icons.
Search hits are displayed in the next section. Each term or phrase in the search hits. To jump to the previous or next instance of a particular hit, click the left or right arrows next to that hit.
At any point during review, you may create your own custom search terms that you wish to be highlighted. Type your desired term into the "Search document" input field, then press enter on your keyboard; your term will be added to the "Custom Hits" list. You can use all of the same advanced search features supported by the contents search term in the query builder: phrases, fuzzy searches, wildcard searches, proximity searches, and regular expressions.
Custom hits exist in two states: pinned and unpinned.
- Pinned hits will be retained for every document you view in the project.
- Unpinned hits will only be searched for in the current document, and will disappear once you move on to a new document.
By default, custom hits are unpinned. To pin a term, first click on the term to open the options panel, then click the pin icon so that it is colored in. To unpin, click on the pin icon again so that it is no longer colored in.
If you need to search for common patterns of personally identifying information, such as social security/government id numbers, phone numbers, credit card numbers, and email addresses, you can use the default regular expression options in the “Search Document” field. Clicking on the input box will bring up a panel containing the three options. Clicking on one will add it as a custom hit.
You can also perform redactions directly from the option panel that appears when you select a term or phrase from the custom hits list. The first redaction option allows you to redact the currently highlighted instance of the term. The second redaction option allows you to redact all instances of the term that occurs in the document. Finally, the last option allows you to remove all redactions, if any, of the term in the current document.
Project admins may want the same term, or set of terms, to be highlighted for all reviewers in that project. They can set up persistent hits, which will be visible for all users in the project. These terms will appear in the persistent highlights section.
You may navigate through persistent hits the same way you would navigate through search and custom hits. However, unlike the other hit categories, only persistent hits found in the document will be displayed in the persistent hits section. For example, if “energy crisis” is a persistent hit in your project, but the phrase does not appear in the document you are currently viewing, it will not appear in the persistent hits section. If you are interested in capturing all documents that contain persistent hits, you can create searches for this purpose from the persistent highlights tab in Project Settings.
