Search Tests

Search Testing is a servlet. Used to fine-tune ranking values and functions. Contains 68 ranking functions, based on the apache nutch project, grouped by

• Term-weighting functions
• Term-distance functions
• Query-independent features
• URL based Functions
• Web-graph based functions
• Temporal features

On the basis of these functions and boosts values, we can assign to each function to refine the ranking of a given query. There are three general parameters for the search

• Number of query matches ( -1=all; -2=default)
• Number of matches returned:10 (<=100)
• Number of matches from the same site returned: 2 (0 shows all)

Finally we have a field to insert the query (query) on which the functions will act.

For each answer we can verify the preserved document by clicking on the respective link The "other versions" link redirects to the version table of arquivo.pt.

The "explain" link redirects to a page where it briefly explains the metrics used for document ranking.

Here is an example.
