Search qualifiers #
Search for a specific keyword
For example if searching under title and qualifying by key work under the term “cow” Results that come back will include all items that have “cow” anywhere within the 245,246 or 247 tag, this will not include results with “cows” in the title.
Exact match #
An exact value search.
For example if searching by Title and qualifying by exact match under the term “cow” the result will come for that specific tile and will exclude results called cows or with additional content such as “the cow that jumped over the moon”
Starts with #
In order to find ‘Starts with’ matches on a title – given that the title can be a 245, 246, or 247 tag, etc. the application must look at a table in which these fields are browsable. This is the Headings table.
The Headings table has 3 variations of the term which are used for various purposes:
- 1. The filing term
- 2. The punctuated term
- 3. The raw Marc term
In these parallel examples, you can see that the structured filing sequence is different from the simple punctuated sequence.
The filing sequence can be either be structured to conform to ALA filing rules (default) or in the Library of Congress Rules filing sequence.
The following special routines are used in construction of the filing sequence:
- 1 Roman numerals: this routine allows for the interpretation of Roman numerals as their Arabic equivalents. It is applied to special subfields where only Roman numerals are likely to be encountered, such as for Kings or Popes, and is not applied to titles including Roman numerals, as in such a case it is impossible to determine whether the characters are indicative of a number or of text: vi = 6, or a Unix text editor?
- 2 Dates of people. This routine provides for interpretation of dates associated with a person, so that identical names may be sorted according to the characteristic of the date (e.g. exact date, ‘flourished’ date. birth date, death date, or approximate date).
- 3 Dates of conferences. This routine provides for the ordering of conferences by the first date.
- 4 Mac and Saint. If special filing according to variant forms of a patronymic or other preliminary word is required, then special routine 4 may be invoked for the specific subfield.
- 5 Dates in subjects. This routine is used to provide for comprehensive chronological filing of subject headings according to internal dates. Particular features of this routine are its ability to handle BC dates correctly, to handle date ranges whether open or fixed, to expand abbreviated date ranges, and to handle centuries in headings.
The structure also files subfields in the correct sequence if this is appropriate.
