On mac os x 10.10.5 with adobe CS6 latest update doesn't seem to find anything on a NAS Synology server with DSM 6.1 software.
Same problem with CC (trial version on latsest OS X version)
I search on the internet and on forums worldwide but did not found this issue.
The search function in finder seems to work ok on the NAS.
also in other software like excell it works also oké.
only on adobe software the search function does not work on our NAS. DS416 from Synology.
You're not speaking to Adobe in what is primarily a user forum. You can file a bug report here:
By the way, CS6 will never be fixed because it's end-of-life software. Any bug fixes would be in the current version of InDesign CC.
