    Area of Science:

    • Medical Informatics
    • Information Science

    Background:

    • Indexers often utilize subheadings more frequently than their main headings.
    • Analysis of selected subheadings revealed a higher usage compared to equivalent main headings.

    Purpose of the Study:

    • To evaluate the impact of subheading usage in information retrieval.
    • To determine the efficiency of searching subheadings independently.

    Main Methods:

    • Comparative analysis of subheading and main heading usage by indexers.
    • Examination of search retrieval when subheadings are treated as unbound headings.

    Main Results:

    • A significant portion of subheadings were posted more frequently than their main headings.
    • One-third of analyzed subheadings showed twice the postings of their equivalent exploded main headings.

    Conclusions:

    • Searching subheadings as unbound terms can enhance search retrieval.
    • This strategy offers an efficient method for increasing the visibility of indexed information.
