Hi: I am trying to search PubMed abstracts which contains BOTH two terms: COL4A1 AND Ocular. I am using the following code:
url= "http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi?"; search = paste(url, "db=pubmed&term=COL4A1+AND+Ocular[abstract]&retmax=300", sep="") docId <- xmlTreeParse(getURL(paste(url, search, sep="")), useInternalNodes=TRUE) I want to get the reply where BOTH the terms exist in abstract. But it is not doing that now. Any idea?
