Hi Ted,
That is definitely not normal, the plugin does search the page contents by default. Make sure that the search in the content fields is enabled.
If the page contents are dynamically generated or outputted via shortcodes, custom codes or anything similar, then you may want to consider using the index table engine.
In those cases the page contents are not actually stored in the posts database, therefore they are not searchable. The index table engine will collect the processed page contents for the output and index it’s contents for searching.
