Searching as a Main Text Field

If it is desired that a Text Parametric Search field should be searched in conjunction with the standard text fields (i.e. Title, Meta, Body) during a text search, then it must be added to the standard search index's text fields. Update the Index Fields setting (here) on the All Walk Settings page, and add the desired field. Only the fields specified in Index Fields will be searched by the main text query.

For example, if there is an Author field defined that contains the name of the author of each document, and it is desired that a text search also check that field in addition to Title, Meta, Body etc., then add Author to the Index Fields setting.
