Background
Prior to OpenMRS version 1.8, the search widgets were written with dojo which involved writing a separate javascript file that extended the parent openmrsSearch for each Openmrs Object if it were to be searchable on w web page, the dojo widgets would fetch all hits in one ajax query which would take sometime making the widgets slow. In 1.8, this was changed by introducing a single and more generic search widget written with jquery with the enhancements below:
How to include a search widget for a domain object in a jsp
This can be relatively trivial if the domain object already has the required methods for the search widgets to work as expected. Let's assume you wish to add an encounter search to you jsp, below is what you need to do.

The arguments passed to the widgets are to used to customize the widget properties, in the example above, 'searchLabel' specifies the label that appears to the left of the search input box, 'searchPlaceHolder' specifies the text to to display inside the input box as a place holder, 'searchHandler' specifies the javascript function to be called to fetch the hits from the server, the properties of the objects in the returned list should match the field names specified for the fieldsAndHeaders property.
