Accessing and Using Data

Text comparison operators can also reference the following automatically populated document fields:
• title
• key
• url
• vdksummary
• author
• mime-type
To explore how to use document fields to refine a search, consider the following database table, named Calls. This table
has four columns and three records, as the following table shows:
call_ID Problem_Description
1 Can't bold text properly under certain conditions
2 Certain optional attributes are acting as required attributes
3 Can't do a File/Open in certain cases
A Verity search for the word certain returns three records. However, you can use the document fields to restrict your
search; for example, a search to retrieve HomeSite+ problems with the word certain in the problem description.
These are the requirements to run this procedure:
• Create and populate the Calls table in a database of your choice
• Create a collection named Training (you can do this in CFML or in the ColdFusion Administrator).
The following table shows the relationship between the database column and

You begin by selecting all data in a query:

Select * from Calls
</cfquery>
The following code shows the

A short description is conceptually equivalent to a title, as in a running title of a journal
article.
This field refines the search.
