Question about storing the CB-Data in the properties field

Hi Mark et al,

Bobray has released a new CustomSearch extra, that makes it possible to search and replace in a huge number of fields in resources, chunks, snippets, etc. Of course changing the content field does not work with contentblocks as it is generated by the CB data in the properties field when saved (if I understand correctly).

In a test version he send me there is also the possibility to search and replace strings in the properties field. I thought it might be possible to use it to search and replace in the properties field to manipulate text in CB. But this does not work. Strings are found in the properties, but replace (via PDO) does not change them. The question is if there is any plugin in CB that might prevent this extra from making changes in the properties field?
