Clustering on copy fields
I have defined a copied field on which I would like to use clustering. I understood that the destination field will store the full content despite the filter chain I defined.
Now, I have a keep word filter defined on the copied field.
If I run clustering on the copied field will it use the result of the filter chain, i.e. the tokens passed through the keep word filter or will it run on the full content?

This is understood.
My question is: I have a keep words filter on field2. field2 is used for clustering.
Will the cluster algorithm use „some data“ or the result of the application of the keep words filter applied to „some data“.
Cheers,
Thomas

copyFields are completely independent. The _raw_ data is passed to both. IOW,
<copyfield src="field1" dest="field2">
sending
<field name=field1>some data</field>
is equivalent to this with no copyfield
<field name=field1>some data</field>
<field name=field1>some data</field>
Best,
Erick
