Meta- search descriptions

 I was just looking into couple of search engines like
indeed.com or bixee.com and I really got surprised the
accuracy of information they have built in their indexes and
also they provide for search result. 
  I have same sort of requirement to build indexes for all
my cleints site and provide search capability. WHile
indexing a page, parser should know the format/structure of
the page, then only it would be possible to index a page
accurately. If site changes their content structure quickly
then crawler/indexer also has to change the meta-info i.e.
format about the page. 
   
  I am basically developing a way of indexing my client
pages to provide search capability with accurate information
(like there are number of products in a clients page and I
need to get all product data and index accordingly). Hence I
need some sort of Indexing which will depend upon meta
search information (Basically describe the content of pages)
like the way I have described above and indexer will work
based on meta search information.  
   
  Can anybody suggest me whether this is possible or not.
   
  regards,
  BR

Why not index their database directly?
