Analysis
1. The ue_01 log had the same z98 / z980 number in every case:

INTERNAL LENGTH NOT CORRECT!! 007000054464

(The first three digits are the "W-nnn" number of the word index.) Checking the fcl01 tab00.eng, we saw that "W-007" is "WNO".

2. Use util f/4 to determine that the problematic word, "21cm" in the example

enter file name (or q to exit) z97
new key = K, exit = Q, continue = RETURN
> k
key 1 = 1, key 3 = 3
> 3
enter start word position nnnnnnnnn
> 000054464
-21cm -000054464-000054464

3. search for "wno = 21cm" in the GUI (4004 hits) and save the results on the server.

4. Use the following sql to determine that there was 1 z980 and 7 Z98 records with this word number:

SQL> select * from z980 where z980_rec_key = '007000054464';

SQL> select * from z98 where z98_rec_key like '007000054464%';

5. as an extra precaution back up the Z98 and Z980 using p_file_03

6. Ask Ex Libris Support to use SQL to delete the problem records

7. Restart ue_01 to process the accumulated Z07s

8. Use the saved GUI search set as input to p_manage_40 (to re-index the records containing "21cm" in a note field).
