How to include MLS/Importer addon fields into the search widget?

Some host providers have limitations on maximum sent parameters or post size etc. Therefore some of our clients have some issues while saving search widget options because the search widget sends many parameters to the server for saving. As a solution, we hid MLS/Importer addons fields in the search widget by default.

If you want to include these fields in your search widget, you should enable desired fields in the search widget first. For this, you can go to WPL->Flex->MLS Addon or WPL->Flex->Importer addon and click on the edit icon of desired fields and set the Search widget option to "Show" instead of "Hide". Please check the below figure.
