java - Meta Search Engine Architecture -

The question was not quite clear, I think; Here's a straightforward update:

What are the common architecture used in the creation of a Meta search engine and is there any library available to build that search engine?

I am looking at the creation of an "enterprise" type of search engine where indexed data can come from the ownership (such as autonomy or Google box) or public search engines (like Google Web or Yahoo Web).

If you see, you will see that its architecture is normal and optimized for meta-search engines. can be done.

Update:

Any architectural sketch is something like this:

  + ------- - ------------------ + | | | Meta-search engine | + --------------- + | | | | | + ------------------- + | --------- | Configuration | | | Query processor | | | | | | | | + --------------- + | + ------------------- + | + ------------- + ------------- + | + ---------- + --------------- + + - + ---------- + ------- - ----- + | | | | | | + ------- + ------- + | | | | Cover | | | | | | | | | + ------- + ------- + | | | | | | | | | | | + ------- + -------- + | | | | | | | | | Search Engine | | | | | | + - + | + ---------------- + | + --------------------------- +  

The parts shown are:

< UL -

Meta search engine - The engine is fully powered. Question Processor - The part of the engine, solves the capabilities, sends the request and connects the results of specific search engines (via wrappers).

Wrapper pulls Meta-Search Engine APIs for specific search engines. Each cover works with a specific search engine, reveals extenal search engine capabilities in the Meta-search engine, accepts and responds to search requests.

Search engines - External search engines for queries, they come in front of meta-search engines through wrappers

Configuration - The data that configures meta-search engines, For example, which rapper to use, where to find more rapper, etc. You can also configure wrappers.
