An error has appeared in the intermediate filter described in this article (Table 1, page 165).

The summating search (line 19) combines the lines 17 or 18, which means 1-7 or 17. Lines 8 to 16 are therefore ignored in the final results.

After contact with the authors of the article it is unclear whether this is a results of copyediting, or that this was present during the research. The results for the intermediate filter are therefore unreliable, and it is recommended not to use that.
