public class QueryTest
extends SEMain

QueryTest is a set of utility methods and a query interface to operate on an index. Run QueryTest with the "-d " option specifying an index directory. Queries can be issued by simply typing the query and hitting return. By default, the top 10 results are displayed. Each line will show the partition number, document ID (within the partition), and the document key that was specified at indexing time. The data displayed can be changed with the ":display" command. Arguments to the display command can be the names of any saved field or any of the following:

• score: the score, between 0 and 1, of the result
• dockey: the key of the document
• partNum: the partition number that the result occurs in docID: the id number (within the partition) of the document
• dvl: the length of the document vector

In addition, you can put "\n" or "\t" for a newline or a space. Arguments should be separated with spaces. The number of results displayed can be changed with the ":n" command.

By default, results are sorted according to their score. Results with the highest score are printed first. The sorting specification can be changed by using the ":sort" command and giving it a sorting spec, as defined in the SearchEngine interface. To get the default sort back, use ":sort -score".

To see the full set of commands available, use the ":help" command. To exit QueryTest cleanly, use the ":q" command.
