How is it possible?

[Bruno Mannina]

Hi All,

In my Schema.xml I have:
<field name="patent-number" type="text_general" indexed="true" 
stored="true" required="true"/>
....
....
<uniqueKey>patent-number</uniqueKey>
....

And when I do on my Admin Page:
patent-number:BE858458A1

then I get two identical documents ?!!!

May be I run twice:
java -jar post.jar BE.xml

but as Patent-Number is a uniqueKey the second indexation will have no 
effect when identical patent-number are found?! no ?

Any ideas ?
Thanks,
Bruno
