Open Source Document Management System | OpenKM

Hi,

We suddenly seem to have a problem with Search which was working fine before. We have folder structure like shown below,
We are trying to search like,
But the search results with nothing, it was working good before. Does search have anything to do with having more folders and documents in OpenKM? We are searching by folder name only.

Thanks in advance!

We have upgraded Tomcat 7 to 8.5 recently, if that causes any problem?

Yes, the problem seem to be because of Tomcat version, because it works in version 7 but not 8.5, what is the Tomcat latest recommended version for OpenKM Community 6.3.2?

The OpenKM tomcat bundle comes with tomcat-7.0.61 I suggest this version. About indexing problems, I suggest go to administration > tools > and choose rebuild index -> choose the rebuild lucene index. It will take some time, but the lucene search index will be entirely rebuild ( that usually solves the problems when the search engine goes in a non stable status or corrupted ). Consider look which java uses for starting the application ( java 1.7 or 1.8, I do not suggest to try with upper versions ( us we have not still jumped to it ).

Finally look at the catalina.log file ( starting application log -> if you see some error or while you are doing a search if you observe that something goes wrong ).
