Any good(comprehensive) article on how to create a customised search engine

for my homesite ?? (also, how can i create a search for my xml database files
which returns specific nodes upon a search match .. please help me with this one ..)

are u talking about a big search engine with spider? or just search engine to search thru ur articles?

well,
I tried my hand on the IIS Indexing Service Search ..
somehow didn't like it much .. too many 'internal' complications
So i wanna code one from the scratch ..
for all the articles (which I have in XML form) XML search is easy to make but i want one for the other stuff and one generalised search for my complete site (me quite ambitious !)
thankz ..

Well, if you have 'internal' problems using Index Server, you most likely wont be able to use your own searching either. If that is you mean in terms of server restrictions. Also, it would be a complicated task and you wouldn't be able to achieve near the power of Index Server.

What I would recommend you doing is having data stored in a database as an index only. Keep on using the XML files, just also store it in a database, making sure to reference the XML file it corresponds to. Then you can use standard SQL statements such as "LIKE '%Word%'" to return your results.
