Controlling an Active Server Pages Search

This section shows how to control searches with an ASP page. The code displayed here is equivalent in function to an .idq file.

This section is executed only if the SearchString variable has been set (that is, only if you have typed a query into the form and clicked the New Query button). This section contains many of the same elements as the sample .idq file in Controlling the Search (.Idq File). Notice the differences in syntax.

set Q = Server.CreateObject("ixsso.Query") and set util = Server.CreateObject("ixsso.util")

These lines define the server-side Query and Utility objects. The rest of the commands in this group can then refer to these objects.

Q.Query = SearchString

Sets the query string (restriction) used to search all virtual directories on the server.

Q.SortBy = "rank[d]"

Sorts the results of searches in rank-descending order (highest rank first).

Q.Columns = "DocTitle, vpath, path, filename, size, write, characterization"

Indicates the kind of information returned in the results.

util.AddScopeToQuery Q, "/Myfiles", "deep"

Restricts the scope to the listed virtual directories. In this example, Indexing Service searches documents in the directory Myfiles, as well as all its subdirectories ("deep").
