The include_subtag_text index parameter

Use the include_subtag_text parameter to index XML tags and subtags as one string. The include_subtag_text parameter is useful when you want to index text that has been formatted with bold <b></b> or italic <i></i> tags.

Use the include_subtag_text parameter with either the xmltags parameter specified or with the all_xmltags parameter enabled.

To view the fields that you have indexed, use the bts_index_fields() function. See bts_index_fields() function.
