How can I import several taxonomy term values into a single term_reference field using the feeds module?

I'm using the feeds module on a drupal 7 instance and I have a content type with a term_reference field with the option to include multiple tags. My question is, how can I import multiple tags from a CSV file with the feeds module? I tried by adding more sources for the s开发者_开发问答ame target, terms are created on the database but only the last one remains on the created nodes.

Use Feeds tamper module to add explode function to mapper and map EACH entry(in this case, separate multiple values for single field by a pipe or similar).
