You can pass the to_tsvector two parameters. The first appears to be a dictionary and the second text. Isthere by chance an English HTML dictionary? That way html tags or html attributes would be ignored. I believe all the built-in text search configurations ignore HTML tags by default, since they have no mapping for the "tag" token type that the built-in parser reports those as. You could of course make a custom configuration that acts differently. regards, tom lane
