Use the Project Search tool to search for text and patterns in all elements of your project, not only in the documents that you added. The search can be restricted to certain fields, like name, author, date, comments, and content. Search terms can contain regular expressions (GREP). See Regular Expressions (GREP).
You can open the tool in the Project Explorer on the left-hand side. Click on the magnifying glass.
Enter a search term. If you use regular expressions, activate the Use RegEx option. You can also select whether a search term should be case-sensitive or not.
Select the entities you want to search in, and select whether you just want to search in the entity name, comment, or the full text content.
Select whether the search results should be expanded to words, sentences, paragraph, chapters (= at least one empty line between paragraphs), or the entire document.
The results of the search are immediately visible. When you double-click on a result, it will be displayed in your project.
