Information
After installation, the Elasticsearch program library used for ELO iSearch requires sufficient memory to re-index the documents for the full text search. An Elasticsearch index for one million data sets (documents) in ELO requires approximately 10 GB of disk space. If you have a 10 GB index, you will required an additional 30 GB of storage space for reindexing to create the index and for the Optimizer. You can use these figures as a guideline if you need to calculate storage requirements for installations with more documents.
