Description:
We are testing the enrichment of bib records with Table of Contents. We have set the 505 $$t to be indexed in the TIT browse in tab11_acc and in the WRD keyword in tab11_word in our Test instance and loaded 200 test records and indexed them.
The keyword indexing is working but we are unable to retrieve records based on the 505 $$t in the TIT search.
When I do UTIL-F-1-29 on a sample record, I see this below for the 505 $$t for record 001444927.
It seems to say that it is indexing the $$t in TIT but I'm not sure the entry looks correct.
Regardless the search for any of the $$t fields doesn't work.

Resolution:
The 505 $$t starts "tanthropology of art : a reflection on its history ..." and that entry is in the browse index:
01 z01_acc \
02 z01_rec_key \
03 acc_code ..............TIT
03 alpha .................L
03 filing_text ...........ANTHROPOLOGY OF ART A REFLECTION ON ITS HIS
03 filing_sequence .......74252
02 z01_acc_sequence ........013474252
02 z01_hash ................797287326345
02 z01_aut_tag .............
02 z01_rec_key_4 \
03 aut_library ...........-CHK-
03 aut_doc_number ........000000000

The problem is that you are expecting to see each $$t SUBFIELD as a separate entry in the TIT index. This isn't how standard indexing works. If you say to use 505 $$t, all of the $$t's are strung together to create one entry in the TIT index.

You can set up your tables to index each $$t as a separate entry using tab_expand_extract to create a virtual field (say t505) for each subfield $$t. And then you index the virtual field t505 in your standard indexing tables. See the Configuration Guide for more information on this table.

If you are using tab_expand_extract for this purpose, be sure the associated expand_doc routine is being invoked in tab_expand. For the browse index, you need this line in tab_expand:
ACC expand_doc_extract

If you are using tab_expand_extract to manipulate fields destined for the direct index, you need this line in tab_expand:
INDEX expand_doc_extract
