Editor's Notes
- Get an idea about search engines Get some terminology and see how it works Put some order in the vast world of Elasticsearch Get ideas of what can/can’t be done with Elasticsearch Enrich your toolbox with some useful utilities and tools
- To tell you about our cool Global Search service To share how we are using Elasticsearch in ALM To provide you with basic milestones on the Elasticsearch road To share how to avoid pitfalls and how we go about some
- Show file system tree view cluster.name: <כשהתחלנו השתמשנו בדיפולט וראינו שכלום לא מתאנדקס מכיוון שהיה עוד קלסטר עם אותו השם ברשת> When nodes started they search for others who are registered to the same cluster. You can run many nodes and many clusters on the same machine, though it is not recommended it is comfortable for testing node.name: <generated out of marvel characters DB better have it unique when you look at logs it helps a lot> bootstrap.mlockall: locks java jvm memory and do not let it swapping its memory which decrease performance network.host: <will allow traffic only from poor means of access control>
- Sorted list of all unique terms Quick and quick are the same word fox and foxes / dog and dogs; They share the same root word. jumped and leap are synonyms. Searching +Quick +fox wouldn’t match any documents
