The default language for Verity collections is English. To index data in one of the
supported languages, you must select the language from the drop-down list when you
create a collection on the ColdFusion Administrator Verity page. You must then enter
the selected language as a value of the LANGUAGE attribute in both the CFINDEX and
CFSEARCH tags used against that collection.

Steps in Creating a Searchable Data Source
There are several steps in creating a searchable data source:
1. Create a collection.
This can be done either through the ColdFusion Administrator or
programmatically.
2. Populate and index the collection
This involves selecting the data and generating the index.
3. Design a search interface and a results page so that users can access the
searchable data source.
Creating a Collection
The Verity engine performs searches against collections. A collection is a special
database created by Verity that contains pointers to the indexed data that you specify
for that collection. ColdFusion’s Verity implementation supports collections of three
basic data types:
•
Text files such as HTML pages and CFML templates.
•
Binary documents (see the Supported File Types list).
•
Result sets returned from CFQUERY, CFLDAP, and CFPOP queries.
You can build a collection from individual documents or an entire directory tree.
Collections can be stored anywhere, so you have a lot of flexibility in accessing indexed
data. This adds enormous value to any content-rich Web site.
ColdFusion provides twodifferent ways to create a Verity collection. You can:
•
Make selections on the ColdFusion Administrator Verity page
•
Code the CFCOLLECTION tag
