Summary

0000715: UNRESOLVED_PATTERN when searching.

Description

Often I get this when searching.
1-34 of -UNRESOLVED_PATTERN- ; (-UNRESOLVED_PATTERN- local, -UNRESOLVED_PATTERN- remote), -UNRESOLVED_PATTERN- from -UNRESOLVED_PATTERN- remote YaCy peers.

Seems to be happening more often if I for example have crawler monitor open in another tab.

Running an homebuilt version of Yacy, compiled from source some months ago.

Additional Information

The following was in the log was in the log when I had the issue, hopefully it is of some interest.

Notes
(0001371) BuBu (developer) 2017-01-06 06:55	In general, every issue which can be reproduced and fixed within YaCy is sure of interest. The log you provided points to a Solr (underlaying index) issue or a problem with the query or content of the result in author_sxt field. This is likely not possible to fix within YaCy, I guess. To reproduce one would need the query term and the results you got. So in this instance it seems to be a very individual issue (according to log snippet).

(0001372) BuBu (developer) 2017-01-06 07:38	fyi: after digging deeper I found one possible YaCy related reason (with the author_sxt facets). I'll follow-up on it.
