This is one of the many reasons why translation memories are great resources – you can search for smaller units in them directly and see in which segments these units have previously appeared and how they were translated in those segments. You can start this process by selecting the word(s) you are looking for and clicking Concordance in the Operations menu. Besides a sequence of words, you can also search for parts of words, or segments that contain all the words you specified. Using the concordance feature, you can only search within the source language entries of the translation memory. To search in target language entries as well, use the translation memory edit view instead.
