Search Scope and Search Criteria

Search Scope and Search Criteria

The above example of search phases illustrates the concepts of search scope and search criteria. The search scope is the portion of a document where the Script searches for an anchor. The search criteria are the rules by which the Script finds the anchor within the search scope.
In the initial phase, the Script starts searching for the
Marker
anchor containing
First name:
at the beginning of the document. The search scope for this anchor is the entire document. The search criterion is that the anchor must contain the text
First name:
.
The search scope for the
Last name:
anchor starts at the end of
First name:
, and extends to the end of the document. The search criterion is that the anchor must contain the text
Last name:
.
In the main phase, the Parser interpolates the
Content
anchors between the
Marker
anchors. The search scope for the
Ron
anchor extends from the end of the
First name:
anchor to the beginning of the
Last name:
anchor. Assuming that the Parser uses a space-delimited format, the search criteria are to retrieve all the text in the search scope, after the leading space character and before the second space character.
The search scope for the
Lehrer
anchor is from the end of
Last Name:
to the end of the document. The search criteria are similar to those for the
Ron
anchor.
We can add this analysis to the anchor table that we presented above. The table now describes the complete method by which the Parser finds the anchors.
