Hello, Ingrid,
You can also create an entry in a personal checklist. Every time the term “numerization” appears in the source, it will bring all the segments that contain that term and you can check there the translation of each instance.
Hope it helps!
To add a search to a checklist, just run the search. Then, click the Add Last Search to Checklist… link at the right of the Search options toolbar.
To show the search options toolbar, click the Search tab and go to View > Show Toolbar.
