Please permit the customization of the "Field" and "Value" columns within the Search Results dialog.

According to your own documentation, "The first column in the Results window shows the value of the display field attribute from each map layer. You can customize the display field you want to use in the map service."

We have tried to alter the "Display Field" as per the notes in your documentation, and if that worked as intended then we would would be happy with the product's functionality. But this does not seems to be the case...

After submitting a ticket "TS021245128" we have been told that this is not in fact the way this operates. We have been instructed that "In the Results attribute table, the first column shown is driven by the layer’s Esri Object ID field (the field whose type is esriFieldTypeOID, often named OBJECTID). Maximo reads that field from the layer’s metadata and uses its value in the table."

Displaying the Object ID to our field users provides them no meaningful information, and in fact may confuse the users to a point where they avoid using this functionality entirely. We are providing a plethora of accurate attributes through this integration. If we could instead display the Asset ID or Maximo AssetNum, this would be infinitely more valuable than displaying a system maintained random number. It's surprising and disappointing that we are unable to alter the attribution we are displaying to our field user within this selection process.

My idea is that you remedy this functionality to act in the way your documentation say it operates.
