Sorry for the title, no pun intended
This thread is all about search engines:
- How to add/fix SEs to GSA
- Recommendations of SEs in general
- Which SE to use for what purposes (scraping, project searching)
- Results of tests (search results, speed,...)
I think that there are many misconceptions regarding the use of search engines. Too many user are just hitting the "use all english language" button and oversee that not all search engines give you good results for your purpose or might even slowing down GSA. Because of that I want to share my thoughts and experience about this topic.
First of all let me say that if you are using Google only you will miss a lot of targets. Google may be the best SE to use because it is fast, give good results and supports all advanced operators like "inurl:" or "intitle:". But many SEs support the most common operators too and give different but also good results for your search terms. This means that you will find more targets to post to altogether.
To get an idea what "advanced operators" are and which effect they have in your footprints, you should take a look at the Google Guide
To know which operators are supported by GSA and the search engines you have to take a look into the "se.dat"-file you'll find in your main directory of GSA (...\Program Files (x86)\GSA Search Engine Ranker). You can open that file with a text editor of your choice and will see which SE is supported by which operator ("site=", "inurl="...).
