> Is there a preferred way to search text within an HTML document?  I have been reading up on searching via to_tsvector.  You can pass the to_tsvector two parameters.  The first appears to be a dictionary and the second text.  Is there 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.
