The INPUT_TERM_PROP_NAME pass-through is used for a corpus that contains pre-tagged records.

Pre-tagged records are source records with pre-existing terms that were generated by non-Guided Search software. In this scenario, you do not want to extract new terms from the documents but do want to perform corpus-level and/or record-level filtering on the pre-tagged terms.

This pass-through can be used in conjunction with the TEXT_PROP_NAME pass-through to combine the pre-existing terms with the new extracted terms.
