We have performed an exploratory case study to understand how subject indexing performed by television production staff using a semi-controlled vocabulary affects indexing quality. In the study, we used triangulation, combining tag analysis and semi-structured interviews with production staff of the Norwegian Broadcasting Corporation. The main findings reveal incomplete indexing of TV-programs and their parts, in addition to low indexing consistency and uneven indexing exhaustivity. The informants expressed low motivation and a high level of uncertainty regarding the task. Internal guidelines and high domain knowledge among the indexers does not form a sufficient basis for creating quality and consistency in the vocabulary. The challenges that are revealed in the terminological analysis, combined with low indexing knowledge and lack of motivation, will create difficulties in the retrieval phase
