configure user defined scores

> It is possible to configure multiple <B

however only one of them can be used during search time.
The <TT

in every <B
CLASS="command"
>UserScore</B
> command.
<SPAN
CLASS="application"

<TT

you can run this <ACRONYM

<PRE

> SELECT rec_id FROM url WHERE url='http://hostname/page1.html';

><P
> The second column stands for a user defined score value for this document,
returned as signed integer in the range <TT

The original score
value calculated by <SPAN

>mnoGoSearch</SPAN

<P
></P
><UL
><LI
><P
>A positive user defined value makes the final rank for this document higher.</P
