Error L0002

I can't add a new document to the Lucene index named $INDEX_NAME.

Problem​

I got an error code with the acronym L0002.

Solution​

The $INDEX_NAME variable represents the Lucene index name. Verify the Mercury DB 3.0 (HgDB) system configuration in the lucene.properties configuration file (file location: $MRC_HOME/config, where $MRC_HOME is the path where the product was installed). Check if the values ​​of the parameters:

  • lucene.base.indexDir - the main Lucene index location
  • lucene.base.indexDir2 - the backup Lucene index location

are set correctly, i.e. they represent paths that exist in the server's file system and whether a subdirectory named index exists in them.
