Hi all,
thanks for your replies. I have managed to do this by writing custom
updateprocessor and configured it as bellow
<processor
class="com.test.solr.update.CustomConcatFieldUpdateprocessorFactory">
<str name="field">firstName</str>
<str name="field">lastName</str>
<str name="dest">fullName</str>
<str name="delimiter">_</str>
</processor>.
Federico Chiacchiaretta , I have tried the option mentioned by you but on
frequent update of the document it keeps on adding the value multiple times
which I don't want . In my custom component I checked for existing value and
if its empty then I have updated it by fN_lN.
Thanks a lot for quick replies.
