Google has created a new service, “Custom Search Engine”. I used this service to create a “Halo search” – search on all good sites dedicated to halo phenomena. This service can be used on any webpage (simple script), or on the home search page.
For example, when I try to search Minnaert’s cigar in Halo Seach – I get 3 links, then try to search in a google “Minnaert’s cigar” – 4 link, then in google, but Minnaert’s cigar (without “”) – 341.
You are welcome to use and improve it.
