Use the Language Filter
If you are searching with DEVONagent Pro you may get results in multiple languages because especially technical terms are often the same in English, German, even French. To avoid confusing both yourself and DEVONagent Pro's AI with [insert whatever language you don't understand here] gibberish, use the built-in language filter. Maximize the search window so that the toolbar is visible, then switch to the Settings tab. Select your language of choice from the Language pop-up menu to restrict searched to that language and uncheck Ignore Diacritics if you want to search for words with umlauted or accented characters. This setting is temporary, you can also add this to any search set.
