In a sense. We provide two %Persistent class methods that can help you :
..%PurgeIndices($lb([<IndexName1>[,<IndexName2>[,..]]]))
..%BuildIndices($lb([<IndexName1>[,<IndexName2>[,..]]]))
If you want to change something pertinent to the index it is a good
practice to purge the index entries prior to the change. If you change
the name of the index ('indexOnTitlesSoundex' -> 'indexOnTitlesPhonex')
it is a must, otherwise the purge cannot apply to a non-existent
(according to the modified repository) index.
Example :
#; that will remove _all_ the index entries as defined in
'indexOnTitlesSoundex'
do ##class(Artist).%PurgeIndices($lb("indexOnTitlesSoundex"))
[... do what you got to do & recompile class ...]
#; that will create the new index entries according to your new/modifed
definition
do ##class(Artist).%BuildIndices($lb("indexOnTitlesSoundex"))
#; or (in case you built a new one with a new name ...)
do ##class(Artist).%BuildIndices($lb("indexOnTitlesPhonex"))
Hope that helps
