If your application does not require full-text content search capability, then disabling content indexing comes handy and increases the performance as well.
If you are curious to try out, then follow along.
Pre-requisites
- You have an environment up and running with Alfresco Content Services 7.x and Alfresco Search Services 2.x (Solr6)
- You have administrative privileges
Looking for Alfresco Content Services 7.x with Alfresco Search Services 2.x installation steps? , checkout these posts:
Content and metadata are indexed by default, it is out-of-the-box behavior. There are two ways you can control content/metadata indexing behavior in order to fulfil the search and indexing requirements. We will go over both options.
Control indexing behavior with help of content model aspect:
To control the indexing behavior, you can make use of a content model aspect named "cm:indexControl" which has two properties. These properties indicate whether content/metadata should be indexed.
The value of these properties are set to true by default.
<aspect name="cm:indexControl"> <title>Index Control</title> <properties> <property name="cm:isIndexed"> <title>Is indexed</title> <type>d:boolean</type> <default>true</default> </property> <property name="cm:isContentIndexed"> <title>Is content indexed</title> <type>d:boolean</type> <default>true</default> </property> </properties> </aspect>
You can apply cm:indexControl aspect on the nodes to control the indexing behavior by setting the appropriate properties. Note that, this approach works only for certain types like cm:folder, cm:content and sub-types. You need to keep in mind that, if you have a large number of nodes which needs to be excluded from content/metadata indexing then this option is not a right choice as you will have to apply the aspect by setting "cm:isContentIndexed" to "false" on all those nodes.
In this situation second option (which we will see next) comes handy.
