Adds memory info
| type = success
| text = Content as well as all files uploaded into the system are indexed. For example, [{{fullurl:Special:Search|search=fai|fulltext=Search|profile=all}} a search for "FAI"] lists both the [[Cloning]] article as well as the [[:File:Fai poster a4.pdf|PDF file]] And the file is not listed only because of the file name, but also because of the (indexed) file content. [{{fullurl:S pecial:Search|search=ed%20roman|fulltext=Search|profile=all}} A search for "Ed Roman"] will bring up the Enterprise Java Beans Design Patterns PDF file ([{{fullurl:File:Ejbdesignpatterns.pdf|page=13}} see p. 13 where Ed Roman is mentioned].)

| type = warning

Elasticsearch performs poorly when JVM starts swapping: you should ensure that it _never_ swaps.
Set this property to true to lock the memory: <code>bootstrap.mlockall: true</code> (in /etc/elasticsearch/elasticsearch.yml)
Make sure that the <code>ES_MIN_MEM</code> and <code>ES_MAX_MEM</code> environment variables are set to the same value, and that the machine has enough memory to allocate for Elasticsearch, leaving enough memory for the operating system itself.
You should also make sure that the Elasticsearch process is allowed to lock the memory, eg. by using <code>ulimit -l unlimited</code>.
