now and then I see errors like be below

there are similar ones for

solr.log.2016-01-28:2016-01-28 12:43:26,665 ERROR org.apache.solr.core.SolrCore @ org.apache.solr.common.SolrException: org.apache.solr.search.SyntaxError: Cannot parse 'author_keyword:': Encountered "<EOF>" at line 1, column 15.

solr.log.2016-01-28:2016-01-28 12:43:27,052 ERROR org.apache.solr.core.SolrCore @ org.apache.solr.common.SolrException: org.apache.solr.search.SyntaxError: Cannot parse 'author_keyword:': Encountered "<EOF>" at line 1, column 15.

do I need to worry about these ?

Monika,

I'm also seeing a few hundred of these Solr errors per day in my DSpace logs. Did you ever figure out what was causing them? I tried a full Discovery re-index, but it didn't help. We're using DSpace 5.5.

org.dspace.discovery.SearchServiceException: org.apache.solr.search.SyntaxError: Cannot parse 'dateIssued_keyword:[1983+TO+1989]': Encountered " "]" "] "" at line 1, column 32.

Thanks,

Alan,

never completely solved it - I do not quite remember what I did in the end - I may have reindexed everything

In any case - looking at my logs now I see 200 exception in Dec 1 so far

only a couple different kinds

Caused by: org.dspace.browse.BrowseException: org.dspace.discovery.SearchServiceException: Error while processing facet fields: java.lang.OutOfMemoryError: Java heap space

Caused by: org.dspace.discovery.SearchServiceException: Error while processing facet fields: java.lang.OutOfMemoryError: Java heap space

org.dspace.discovery.SearchServiceException: org.apache.solr.search.SyntaxError: Cannot parse 'author_keyword:': Encountered "<EOF>" at line 1, column 15.

org.dspace.discovery.SearchServiceException: org.apache.solr.search.SyntaxError: Cannot parse 'dateIssued_keyword:': Encountered "<EOF>" at line 1, column 19.

org.dspace.discovery.SearchServiceException: org.apache.solr.search.SyntaxError: Cannot parse 'marilyn mayers, 'A century of psychiatry\: the Egyptian mental hospital' (Ph.D. dissertation, Princeton University, 1982': Encountered "<EOF>" at line 1, column 120.

org.dspace.discovery.SearchServiceException: org.apache.solr.search.SyntaxError: Cannot parse 'subject_keyword:': Encountered "<EOF>" at line 1, column 16.

org.dspace.discovery.SearchServiceException: org.apache.solr.search.SyntaxError: Cannot parse 'title:()': Encountered " ")" ") "" at line 1, column 7.

org.dspace.discovery.SearchServiceException: org.apache.solr.search.SyntaxError: Cannot parse 'title_keyword:': Encountered "<EOF>" at line 1, column 14.

org.dspace.discovery.SearchServiceException: org.apache.solr.search.SyntaxError: Cannot parse 'With a Little Help from my Friends" Examining the Role of Peer Homophily in High School Success': Lexical error at line 1, column 96.  Encountered: <EOF> after : "\" Examining the Role of Peer Homophily in High School Success”

looking at one example I see 

2018-01-05 21:51:10,333 ERROR org.dspace.app.webui.discovery.DiscoverySearchRequestProcessor @ anonymous:session_id=62D95C4F47A190897871E95051B52843:ip_addr=198.91.236.107:search:query=wendy knopps,scope=null,error=org.apache.solr.search.SyntaxError\colon; Cannot parse 'author_keyword\colon;'\colon; Encountered "<EOF>" at line 1, column 15.

Was expecting one of\colon;

    <BAREOPER> ...

    "(" ...

    "*" ...

    <QUOTED> ...

    <TERM> ...

    <PREFIXTERM> ...

    <WILDTERM> ...

    <REGEXPTERM> ...

    "[" ...

    "{" ...

    <LPARAMS> ...

    <NUMBER> ...

Seems like somebody in the UI put a query together : query=wendy knopps,scope=null

there is no indication in the trace that the search is looking for an author

Could it bee that the code add an empty author search term ?

I tried to trigger that in my JSPUI - but was not successful

Any ideas along these lines ?

Monika

Thanks for the response, Monika. I haven't spent much time troubleshooting this but I was assuming it's just some bot that has performed the search by essentially pressing random buttons in the XMLUI. :)

Cheers,
