For some record deleted index entries remain in the database and still can be found whereas for other records newly added fileds (index entries) can't be found.
With rep_ver #019160 in Aleph 22 the number was increased to 20000 words:
Description: A word index for a bibliographic record is defined by the word number + the index type + the exact location in the record , so that a word which appears several times for the same index will be indexed several times. In several cases, the total number of words for a bibliographic record (in Z95) exceeded 5000, which is the limit of words indexes kept in memory for the record. This caused inexact words indexing when updating this record. As a solution, the number of words indexes for a bibliographic record has been increased from 5000 to 20000.
Note: the change is in internal buffers and programs only, not in the Z95 Oracle table: its data is defined as "LONG".
Implementation Notes: If the problem is relevant for a customer, he must run p_manage_01.
As you can see from the description above it's necessary to run p_manage_01 so that the old records can be changed to the new limits.
util f/1/28 can be used to view (and count) the words in a bibliographic record. Note that word-pairs are generated for adjacent words so the number of words is roughly twice what one might expect.
