The Field and Maximum Field modules rank results based on which attribute member of the selected search interface caused the match.
In a search interface, higher relevance-ranked values (in the RELEVANCE_RANK attribute of the MEMBER_NAME element) correspond to greater importance. This behavior means that the Field and Maximum Field modules will score results caused by higher-ranked Endeca attributes ahead of those caused by lower-ranked attributes.
<MEMBER_NAME RELEVANCE_RANK="2">P_Type</MEMBER_NAME> <MEMBER_NAME RELEVANCE_RANK="1">P_Description</MEMBER_NAME>records tagged with P_Type will be ranked ahead of records with P_Description.
To change the relevance ranking behavior for these modules, change the RELEVANCE_RANK integer settings as appropriate. For example, change P_Description to a RELEVANCE_RANK="2" setting and P_Type to a RELEVANCE_RANK="1" setting.
