You can search for text with attributes that are applied either by direct formatting or by styles. For example, if you search for the \<emph\>Font\</emph\> attribute, all instances of text that do not use the default font are found. All text that has a directly coded font attribute, and all text where a style switches the font attribute, are found.
If you want to find text with any font by name, click the Format button in the Find & Replace dialog of LibreOffice Writer.
After you select the attributes that you want to search for, the Paragraph Styles box in the Other options area of the LibreOffice Writer Find & Replace dialog changes to Including Styles.
If you want to search for text in which attributes were set by using direct formatting and styles, select the \<emph\>Including Styles\</emph\> box.
The search criteria for attributes are listed below the Find box.
Choose \<emph\>Edit - Find & Replace\</emph\>.
Clear the Find text box if necessary.
In the \<emph\>Attributes\</emph\> dialog, select the \<emph\>Font\</emph\> check box, and click OK.
In the Find & Replace dialog, you now can read "Font" below the Find text box.
All places where a font change was applied, either directly or by assigning an appropriate style, are found.
To stop searching for the current attributes, reset the \<emph\>Find & Replace\</emph\> dialog to normal mode.
Click \<emph\>No Format\</emph\>.
Searching for attributes is available in the Find & Replace dialog for text documents.
