Apache Solr 6 creates large suggester_input/sort files

[miroslav]

Hello, 

I am importing a large number of files into Alfresco and Solr is trying to create indexes. In the process, a large suggester_input and suggester_sort file are created in the temp Solr folder (50GB for the last two days).

Is this normal behavior and if I turn off the suggester, does it have a significant effect on performance?

I am using alfrescco search services 2.0.1 with default setting.

Thank you!

Hi!

The size of the indixes depends on the amount of documents, nodes and relating metadata. If your content is mainly text-based (Office, PDF, HTML...), your indices can be a substantial (and important) part of the storage, compared to the size of the contentstore.

Relating to the WFSIterator* files in /tomcat/temp, it is usual to deactivate SOLR suggester in <solrRootDir>/workspace-SpacesStore/conf/solrcore.properties (solr.suggester.enabled=false) to avoid these huge files in tomcat/temp. Then, you can clean tomcat/temp and restart Alfresco.

In case you disable the suggester:  if you launch a query on the UI Solr won't suggest you any similar term. E.g.: if you write "Alfresdo", it won't suggest you "Alfresco".

Cheers,

Cris.
