ICT for Library and Information Professionals: A Training Package for Developing Countries
Repeatable field : A field which may occur more than once in a record
Save file : A file used to save the results of a search
Search term : Any of the elements that can be used to retrieve a record, e.g. a
subject descriptor, a name, a word, a document code. The search terms for
the records of a given database are defined in the inverted file FST
Stopword : A non significant word to be ignored when indexing a field (e.g.
articles, prepositions,)
Subfield : One of the data elements contained in a field. A subfield is identified
by a subfield delimiter
Subfield delimiter : A two character code preceding and identifying a subfield of
a field
Tag : A number uniquely identifying a particular field
Variable length field : A field that does not have a fixed length. Instead, the
field length varies depending on what data is stored in it. With variablelength
fields, the fields in each record would be just long enough to hold its
data.
