Coveo REST API keyword not found but it is part of the indexed items
We have a textdescription field in Sitecore. The content is html format. This field is set to "Field Queries" in the Custom Fields in Configuration. However, when I query the REST API, it returns noting even the textdescription field does contain the searched keyword in the html content.
Enabling field query is not the same thing as enabling free-text search.
Field query allows you to perform queries such that you can query by specifying explicitly the field you whish to query on. Your query should have this format @[field][operator]"[value]", ex: @ftextdescription12345=="mars".
What you are trying to do is a "free-text" search. You want your search to look in the content of your field without having to specify the field name. Your field should enable free-text search on your field in your configuration.
