Example 1

The following rulebase fragment

<all weight="80" >
    <text data="trichet" weight="10"/>
    <text data="bob" weight="10" not="1"/>
</all>

evaluated against the following document fragment

Jean-Claude Trichet announced today a rise of 1/2 point in interest rates.

In a separate intervention the governor of the European Central Bank announced that the institution will keep a firm handle on inflation.

Would have a score of “0.80” and 1 evidence phrase (“Trichet”)

Example 2

    <all data="all of these" />

is equivalent to

<all>
    <text data="all"/>
    <text data="of"/>
    <text data="these"/>
</all>

and would have score “1.00” with 3 evidence phrases in the document

This has a sentence with these and all occurring in it. Of course the rule searches for occurrences anywhere in the document.
