google/pubmed searches including all synonyms (that was possible at ihop)

Question

[fuellen]

Hello,

1) For a couple of weeks, ihop (http://www.ihop-net.org/), "Information Hyperlinked over Proteins" seems down, does anyone have details?

2) ihop offered to start pretty straightforward google/pubmed searches including all the synonyms of a gene into the search phrase, connected by "OR", to which the user could then add his/her additional terms, connected by "AND". That was quite useful; is there any other service like that still available?

Thanks a lot for any help!
