可以使用 include_subtag_text 参数在已索引数据中包含格式化标记内的文本。
<comment> this <bold> highlighted </bold> text is very <italic> <bold>important</bold> </italic> to me </comment>
CREATE INDEX comments_bts ON mylog(comment_data bts_lvarchar_ops) USING bts(xmltags="(comment)",include_subtag_text="no") IN bts_sbspace;
comment:this comment:text is very comment:to me
CREATE INDEX comments_bts ON mylog(comment_data bts_lvarchar_ops) USING bts(xmltags="(comment)",include_subtag_text="yes") IN bts_sbspace;
