Hi

I'm looking for some search engine and directory search application
(script) that will be able to create and  search about 300.000 URL's?

Some  of the futures that I need (Not all of them are must, but will
be nice to have them)

1. Indexer so for example if a site is already in the database and the
site have been updated so the indexer will check the site for new
updates and use it in the next searches.
2. I'm trying to target one country only, I know that I can crawl only
specific TLD's but is there something else that can be done  to
achieve that?
3. To show in the search result page how many times a specific world 
have been search and how many results have been found  etc. etc.?
4. To  have some support  for targeting worlds so I can have some kind
of sponsor links, (I  do not need full pay-per-click system) for
example if some one searches for cars and a relevant banner with a
cars advertisement to show up in the result page.
5. To have crawler, indexer, spider.

Also not to be to expensive, maybe not more then $1000

Here is some that I have been looking at but they do not have all the futures.

I already have look at Fluid Dynamics Search Engine but it dose not
look like it will do for me, it support only 10.000 URL's and it dose
not support directory and word "banner" targeting.
