Thanks for the good discussion.
 
I am aware of a number of resources out there for patent search. Some are free while others are not.  
 
My question here is - What is/are offered in the "not-free" resources that the free ones don't have? - is it some better searching tools, or is it some more complete database? Another way to put it - can one do an equally good/exhaustive/thorough search using the USPTO website alone without other "not-free" resources? (what about foreign search?)

Foreign patent databases are made available for search on the pay sites (Delphion/Micropatent at least).  Now these are databases that are generally available on the web freely as well (at least the most meaningful ones), but searching in one spot is easier.  freepatentsonline.com does allow some foreign patent searching.
 
The pay sites also also give you better search tools, make it easier for you to browse through the search results, and extract information from the results.  (As a disclaimer, I have never used Micropatent)
 
Anyways you can use free resources to do an equally exhaustive search, generally, or at the very least, close.  It just isn't as efficient - it can take longer.  But if you are a beginner and don't plan on making a career or hobby out of patent searching, its very possible that the pay sites are not worth the money, in part just because you'll only get so much out of them until you are more familiar with them anyway.  
 
One last note, as far as US patent applications are concerned, in my opinion strict classification searches should be given less weight.  This is just because many published applications are more likely to be classified incorrectly, or at least inconsistently, compared with issued patents.

I have used both Delphion and Micropatent and find Delphion easier to use with better technical support.  System-wise, Delphion seemed to be more stable.

I like the "foundation to a house" analogy to the importance of the initial strategic approach in patent application to its long term effectiveness as a legal document. I understand a "good search" may be the foundation of the foundation.
 
My question is - How to do a good search? - What are all the "stones need to be turned"?
 
I am new to this forum, so if my question(s) has been asked/discussed before please kindly point me to the link. Thanks.

 
 
it looks like I missed a good discussion on this topic, doing patent searches and writing a patent application, and supporting prosecution - sorry I couldn't post then
 
Xdim: you might want to visit: siberkhem.com for information about patent searching and application writing
 
take care, Fran Lorin
