The ExternalSearchEngines table contains descriptions of search engines which
can be accessed to look up a word or phrase within the eTextReader system. This
allows the system to be expanded to use new data sources as reference material.
Note that this system is separate from the internal searching mechanisms which
allow searching through the content making up any given textbook.
Search engines are described using the standard Open
Search mechanism, which
is the same mechanism used by Internet Explorer 7 and Firefox 2.0.
The following is a description of the columns in the ExternalSearchEngines
table, along with their meanings.
