With latest version of AEM, Oak does not index content by default, Custom indexes need to be created as per the requirement.If there is no index for a specific query, possibly many nodes will be traversed. The query may still work but probably be very slow. So let's quickly create a custom Index. We will explore below search features. Synonyms Words Stop Words Autosuggestion PorterStem & Lower Case For Creating Lucene custom Index step please follow below steps Open CRXDE and navigate to http://localhost:4502/crx/de/index.jsp Navigate to /oak:index Create node with jcr:primaryType = oak:QueryIndexDefinition Index must have below properties while creating it must be of type oak:QueryIndexDefinition must have the type property set to lucene must contain the async property set to the value async, this is what sends the index update process to a background thread Click save all and save your changes. Below are the non mandatory but useful properties that we can add for optimized indexing compatVersion - Required integer property and should be set to 2 By default Oak uses older Lucene index implementation which does not supports property restrictions, index time aggregation etc. To make use of this feature set it to 2. Please note for full text indexing with compatVersion 2, at query time, only the access right of the parent (aggregate) node is checked, and the access right of the child nodes is not checked. If this is a security concern, then compatVersion should not be set, so that query time aggregation is used, in which case the access right of the relevant child is also checked. A compatVersion 2 full text index is usually faster to run queries. evaluatePathRestrictions - Optional boolean property defaults to false If enabled the index can evaluate path restrictions includedPaths - Optional multi value property. Defaults to ‘/’ List of paths which should be included in indexing. excludedPaths - Optional multi value property. Defaults to empty List of paths which should be excluded from indexing. queryPaths - Optional multi value property. Defaults to ‘/’ List of paths for which the index can be used to perform queries. Refer to Path Includes/Excludes for more details indexPath - Optional string property to specify index path Path of the index definition in the repository. For e.g. if the index definition is specified at /oak:index/lucene then set this path in indexPath
