====== Add a new Search Engine ======

Let's say you want to add a new search engine like [[http://www.ebay.com/|ebay]]. Than you have to perform the following Steps:

===== 1. Finding the Right URL to Use =====


  * Open that URL in your browser and do a search of your choice that actually delivers many results
{{ :email_spider:email_spider_new_search_engine_browser1.png?nolink&600 |}}

  * Right click on the page 2 link and copy that URL
{{ :email_spider:email_spider_new_search_engine_browser2.png?nolink&600 |}}
  
**__You should now have an URL like this one__**:\\ 
%%http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=%%**<color red>software</color>**&_pgn=**<color orange>2</color>**&_skc=50&rt=nc

The highlighted URL parts the the once that have to be modified before you add it to the program.

  * **<color red>software</color>** must be exchanged with the place holder **<color red>%search%</color>**
  * **<color orange>2</color>** is the page number and must be exchanged with the place holder **<color orange>%page%</color>**\\ You can recognize this parameter by having a look at page 2,3,4... and see what numbered parameter increases. Usually it increases by 1 or by the numbe rof links you see on the page.

**__You new URL will look like this now__**:\\ 
%%http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=%%**<color red>%search%</color>**&_pgn=**<color orange>%page%</color>**&_skc=50&rt=nc

===== 2. Finding the Links to Extract =====

Basically you have two types of search engines.

==== 2.1. Search Engines with external Result-Links ====

These will give you results of external links not belonging to the same domain as the search engine (e.g. google.com). In that case you copy all Links that have nothing to do with the results and make a big mask out of it.\\ 

**__Copy just something from the domains that are irrelevant like__**:\\ 
atdmt.com|google.|googleusercontent.|googleusercontent.|youtube.|blogger.com|schema.org

  

==== 2.2. Search Engines with internal Result-Links ====

These will give you internal URLs that will point to sublinks on the same domain (as in this example). Let's copy like 3 URLs from the wanted result links and see what they have in common.
  

  - %%http://www.ebay.com/itm/Microsoft-Office-2010-Home-and-Student-Retail-Box-3-PCs-NEW-/290923163259?pt=US_Office_Business_Software&hash=item43bc5f2e7b%%
  - %%http://www.ebay.com/itm/Microsoft-Windows-7-Home-Premium-32-64-Bit-Upgrade-2-DVDs-/261269844948?pt=US_Operating_Systems_Software&hash=item3cd4e573d4%%
  - %%http://www.ebay.com/itm/Microsoft-Office-2010-Home-and-Student-Product-Key-Card-PKC-Retail-79G-02020-NEW-/290923160299?pt=US_Office_Business_Software&hash=item43bc5f22eb%%

Exchange everything they have not in common with a "*".

**__Now you should have an URL like this one__**:\\ 
%%http://www.ebay.com/itm/*/*?pt=*&hash=item*%%

===== 3. Putting it all together =====
