Hi Jim,
I have used Lucene search in a project and it is very capable, but also takes some work to implement.
For the search you described, you can accomplish that with native Mendix capabilities in the following way:
Hope that helps,
Mike
Mike is right, you can use a listview for that. In case you want to use the free lucene version (which is not only free, but also easier to deploy)
Please have a look at https://appstore.home.mendix.com/link/app/29220/Appronto/Appronto-Search-Engine This is a Lucene implementation that will let you configure the entities and associations 1 layer deep with the help of the Model Reflection. It's a complete solution including a searchinput field presenting the first 10 results.
In the configuration you have control which attributes are more important containing the data.
