Notes for the subject phrase index (su=) and subject all index (sa=)

Each portion of the subject heading (e.g., subheading in 650/a,m,x) will be handled as a distinct phrase search. The suggested strategy in searching for records that contain those subheadings is to and those terms together.

Example:  650 #a Kidney Tubules, Collecting #x Metabolism is searched by entering:
kidney tubules, collecting and metabolism.

Expert Index Subject All (sa=) index will search all portions of the subject heading as a distinct phrase search.

Example: 650 #a Kidney Tubules, Collecting #x Metabolism is searched in the sa= index by entering:
kidney tubules collecting metabolism - Browse the SA= index for exact terms.

Notes for creating links for Reference Sources

Link creation in the web version is based on the following:

The PMID link is based on the presence of the 590/g tag. If it exists, it is used to search the Accession Number index ( NO:) to pull up the related record. Example record: PMID: 11588343

Indexes

What follows is a list of FirstSearch indexes and the combination of USE and STRUCTURE attributes that can be used to access them.

  1. For any FirstSearch label where multiple USE attributes are listed all the attributes will provide the exact same search result sets.
  2. Any USE attribute that is not marked as a restrictor is available via the SCAN service.
  3. Restrictors are specially implemented indexes and are not available for scanning. Terms for these must be ANDed with other terms to limit the size of the result set. See the table provided for each restrictor to determine valid terms and their associated meaning.
