Normally, all statement results receive the same treatment in the relevancy calculation. However, you may want certain statement types to be weighted higher or lower in the search results. For example, two identical statements from two similar documents usually receive near identical relevancy, with minor differences in the context and document weight factors. However, if the statements are from two different text fields (such as role:goal and role:fact ), and these fields were weighted differently, then their relevancy could vary greatly. ATG Search supports these weighting factors with the following parameters: f*1.0,o*1.0,s*1.0,ROLE:ID*2.0
f* —The weight (or multiplier) of preferred answer statement relevance.
o* —The weight of structured statement results.
s* —The weight of unstructured statement results.
A weight of 1.0 means the original (pure) relevancy is used. Individual structured types (or fields) can be defined separately, as shown: role:goal*1.2,role:symptom*1.1,role:fact*0.5
