Faceting a text field

[Dhanushka Samarakoon]

Hi,

I'm trying the create a facet on a field with full names in it.
When I specified it like this "facet=on&facet.field=InvestigatorName" in the
url I got the first and last names as separate fields in the facets.
<lst name="InvestigatorName">
<int name="john">11</int>
<int name="daniel">3</int>
<int name="jame">3</int>
...
</lst>

Then I changed the schema.xml as follows.
<field name="InvestigatorName" type="text" indexed="true" stored="true"
multiValued="true" />
<field name="fInvestigatorName" type="string" indexed="true" stored="false"
/>
<copyfield source="InvestigatorName" dest="fInvestigatorName"/>

and restarted solr and re-indexed the data.
after that I ran the qry again with the url
"&facet=on&facet.field=fInvestigatorName", but this time got zero results
for the facets.
<lst name="facet_fields">
<lst name="fInvestigatorName"/>
</lst>

Can someone point out if I'm doing something wrong?

Thanks,
Dhanushka.
