The options on the Display Filter toolbar in the Editor view enable you to apply filters to the active document in the Editor window. By default this toolbar is not displayed. To display this toolbar, select [View > Toolbars > Display Filter] from the menu bar.
You can display segments you want by using regular expression in the "Containing:" box.
For example, if you want to display segments which contain any numbers, you can try the following short regex snippet.
\d+
The following example shows how it works in SDL Trados Studio. This will be useful to check whether any number is missing in the target segments or not.
If you want to display any segments which do not end with a period or a question mark in the target segments, you can select "In Target" and try the following :
[^.?]$
And you can also check any segments with consecutive duplicate words (such as "you can click click this icon"):
(\b\w+\b)\W+\1
OR
\b([A-Za-z가-힣]+)\b\s+\1 ;For Korean
In the screenshot above, the lines 6, 9 & 15 should not be displayed. In RegexBuddy, only line 5 & 8 are filtered:
I don't know why those segments which do not contain consecutive duplicate words are also displayed, but I hope this issue gets resolved in the newer version of SDL Trados Studio.
As you see, with simple regular expressions, you can filter segments as you wish.
