Web OPAC results ranking

• Article Type: General
• Product: Aleph
• Product Version: 18.01

Description:
Ranking does not work as expected.

Resolution:
TCU has special configuration that allows ranking (Sorting by Rank) immediately with the results display.
Normally, users search the web OPAC, and then rank the results set.
The ranking is built according to words weight set in tab00.eng, column 9, and the frequency of word's appearance.
For the words ranking to work correctly, the column Rank with the code "RANK" in column 12 should appear in the ./tab/www_tab_short.eng.
The length for this column may even remain 0000.
Problem was resolved after adding this column.
