Problems with solr6 index rebuild and alfresco 6.x

Dear support,

My name is Ángel and I am writing to you from Fundación CARTIF. As I indicated in the thread issue, we have problems with the SOLR 6 engine in our Alfresco Community 6.x

Specifically, we saw the following error in the alfresco.log and tried to rebuild the entire solr6 indexing but it didn't work.

2020-06-08 12:10:23,615 ERROR [org.alfresco.repo.site.SiteServiceImpl] [http-nio-8080-exec-23] LuceneQueryParserException with findSites()
org.alfresco.repo.search.impl.lucene.LuceneQueryParserException: 05080032 Request failed 500 /solr/alfresco/afts?wt=json&fl=DBID%2Cscore&rows=5&df=TEXT&start=0&locale=es_ES&alternativeDic=DEFAULT_DICTIONARY&fq=%7B%21afts%7DAUTHORITY_FILTER_FROM_JSON&fq=%7B%21afts%7DTENANT_FILTER_FROM_JSON

The symptoms are as follows:
- When accessing a site's repository a popup appears with the previous error.
- We get different results with different users when we do a document search in the whole repository. Add that after trying a rebuild of the index now no user finds anything.

We have followed these links:
https://docs.alfresco.com/5.1/tasks/solr-reindex.html
https://www.zylk.net/en/web-2-0/blog/-/blogs/performing-a-full-reindex-with-solr-for-alfresco-ecm

Any idea what might be happening and how to fix it?
Thank you very much for your attention.

Best regards,

Ángel.

Re: Problems with solr6 index rebuild and alfresco 6.x

No hint on the log error you are adding, as the main cause of the problem will be in the SOLR log, not in the Alfresco log.

Related with the re-index, I guess you have not configured your repo for cross locale searches.

You can find a Docker Template available in https://github.com/aborroy/search-services-cross-locale

Also check point 3 in official documentation: https://docs.alfresco.com/search-community/tasks/solr-install-withoutSSL.html

Once you have applied the configuration, you'll need to re-index SOLR again.

Re: Problems with solr6 index rebuild and alfresco 6.x

Hi @angelborroy 

Thank you for your answer. Following the thread https://docs.alfresco.com/search-community/tasks/solr-install-withoutSSL.html I have seen that in point 6, when I try to access http://localhost:8983/solr, I get a 404 error.
The rest of the file configuration is correct.

Therefore, I couldn't continue with the SOLR re-index.

Thank you very much.

Greetings,
Angel.

Re: Problems with solr6 index rebuild and alfresco 6.x

Have you started SOLR correctly?

Is there any error in the logs?

Re: Problems with solr6 index rebuild and alfresco 6.x

Hi @angelborroy 

To start it I simply used the command "./solr start -force" and this is what returns the status of the service:

angel:/opt/alfresco/alfresco-search-services/solr/bin# ./solr status

Found 1 Solr nodes:

Solr process 766 running on port 8983

ERROR: Failed to get system information from http://localhost:8983/solr due to: org.apache.http.client.ClientProtocolException: Expected JSON response from server but received: <html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1"/>
<title>Error 404 </title>

<body>
<h2>HTTP ERROR: 404</h2>
<p>Problem accessing /solr/admin/info/system. Reason:
<pre>    Not Found</pre></p>
<hr />
</body>
</html>

Typically, this indicates a problem with the Solr server; check the Solr server logs for more information.

And here we've got the solr log file:

Re: Problems with solr6 index rebuild and alfresco 6.x

And why are not using what the documentation states?

Re: Problems with solr6 index rebuild and alfresco 6.x

Hi @angelborroy 

Sorry, I did it also and same results:

Search the cause in SOLR logs.

What Java version are you using?
