"Exception while improving searchresult", no results displayed

[ccandreva]

I have a search that is returning an **Exception while improving search result" . Even though a result count is given, no results are displayed. I've narrowed it down to a small search that reproduces the problem.

when it called function "setDocumentInfo", it would throw a exception, and log to log.file.it's not a pretty way to handle it . hope author can change it.

The same error message now appears when a search is done in IOS client 4.4.x (which uses unified search) - breaking the search in the app completely. See #190

[jacotec]

@ccandreva Does your searched file live in an external storage connected to your Nextcloud server?

[ccandreva]

@jacotec Yes, it's a cifs share.

[jacotec]

OK ... so that is related. My issue #190 does also only occur if there is at least one result file on an external share.

From time to time I am getting the similar warning error, eg:
