DialogWeb Help:  The Basic Index

The Basic Index is an alphanumeric list of all words and phrases that can be searched with the SELECT command. Terms can be searched alone or with field suffix codes. A field suffix codes is a two-character code that identifies a field. It is used to limit your search terms or sets to a specific Basic Index fields.  For example, to limit the search term budget? to the Title field, enter s budget?/ti.

Specific fields and codes vary according to the database you are searching. Available fields and codes are listed on the database Bluesheets.

Note:
If a suffix code is applied to a set created with the AND or NOT logical operators, the code applies to at least one, but not necessarily all, of the terms in the set. To ensure the suffix applies to all terms, use parentheses, for example, s (budget? and balance?)/ti. If the selected Basic Index suffix is not supported in a database, the search term will be processed in all valid suffix fields in the Basic Index.
