It is quite easy to find where the field is injected. So, when you add your computed index field there is a node with method in it: <fields hint="raw:AddComputedIndexField">. The AddComputedIndexField leads us to the IDocumentBuilderOptions.AddComputedIndexField(XmlNode configNode). Here you can see that field is created from the type attribute using reflection. This is a place to put your custom constructor behavior with DI.

| Nov 3, 2016 at 8:11 | comment | added | Dmytro Shevchenko | @adb Using the dependency resolver would defeat the purpose of using DI, which is the fact that my modules and components are not aware where the dependencies are coming from. Could you please clarify what you mean when you say I have to override the factory of index class? | |
| Nov 3, 2016 at 8:05 | comment | added | Andrey Bobrov | I think if you want them to be inserted in the constructor (i.e. like in controller), you have to override the factory or index class. The easiest way is to use the standard Asp MVC dependency resolver + parameter-less constructor. p.s. Make sure that you investigate the computed field lifetime because I doubt it is being re-created each time it computes the value for indexing. | |
