Understanding the INDEXRULES field in the Voyager SEARCHPARM table

Question

How can I understand the INDEXRULES field in the SEARCHPARM table?

Answer 

The indexrules field tells how each index in constructed.  It has a maximum length of 300 characters.

Note the following are not necessarily comprehensive. 

Index Type

IX=A for authority indexes, B for bib indexes, C is for composite indexes, E is for name/title indexes, K for keyword indexes, N is for name indexes, Q for MFHD keyword indexes, S for special subject indexes, T for special title indexes, U for call number indexes (from MFHD).

Rule Definition Codes

AL= is a MARC field.

BT=bib text field.

SR= is used with a single, repeatable field and indicates that each occurrence should generate an index entry.

Define Search Parameters

S+= lists subfields that should be included in the index.

S-= lists subfields that should be excluded from the index.

NM= is the normalization rules (the most commonly used character string = (juapih)

NF tells the location of a non-filing indicator.

HL indicates a hard limit, i.e., a limit that is always in effect for this search key.

LN is the Text Length (you may or may not see this)

IDS=Y Appears at the end of the INDEXRULES if "Show Index Column in Search Results" is not checked in SysAdmin for the index
