Use Custom Meta Data Columns to increase the performance of searching the message history on a particular message field.

If there is a particular element of data from your messages that you may need to search by later, configure the channel to map the data into a custom meta data field. Mirth Connect will then index this data to improve search performance when searching for particular values. To do this, first create a mapper transformer step that maps the value into a Channel Map variable ("myField" for example). Then in the "Custom Metadata" section of the channel summary screen, add a new column and assign it to the variable mapping that you defined ("myField").

To search for messages based on values in your custom meta data column, select "Advanced..." to open the Advanced Search Filter. Then add search criteria for the custom field in the table
