You can search for phrases in PubMed  (or article titles) without the problems caused by the mapping feature by searching in Google and adding the search term < +nlm > (without the brackets).

Searching Google for  < "Use of handheld wireless technology for a home-based sickle cell pain " +nlm > brings up the article in 2 places in PubMed and at another site where  the PMID  is listed as the "Nlm Unique ID:."

I find this tip to be very helpful in getting my doctors to look at PubMed, as well as to search for tricky subjects that I can't seem to find any other way.  The first results are usually citations in PubMed and articles at journal sites that include a link to the PubMed citation.

Thanks for the information on how PubMed searches.

Happy searching,
Alice Hadley

Just a brief addition to Michelle's helpful explanation:  
Quotes do not force PubMed to search for the phrase unless it's a phrase in the 'phrase index.'  
I don't begin to understand the process by which the PubMed folks decide when a phrase is ready to become a recognized phrase, but there it is--and that's why the advice to check the details box is so important.

Try this:  "search strategy"  :  this is a phrase, and you will see that the PubMed search engine finds the phrase in all fields.  However, "search possibilities" is not a phrase in the phrase index, and the details box tells you that it searched for each word, ANDing the two sets.

Several years ago, "tear film" was not yet in the phrase index.  "Tear" mapped to various MeSH terms including lacerations; at that time, "film" ended up in the movies.  That's been changed.  A year ago, one could retrieve the article titled "Use of handheld wireless technology for a home-based sickle cell pain management protocol" with a search for "sickle cell" but that too has been changed in the search function.

First, when you type something in the PubMed box and it gives you a
bunch of suggestions, those are NOT real terms.  Those are just popular
items that people have been typing in. I just went to a PubMed update
class today and our instructor said those suggestions are basically like
a Google's I'm Feeling Lucky search.

Second, always go to the search details box to see how your search
panned out within PubMed.  Do is a stop word, so that "term" will not be
searched ever.  Not is a Boolean term not a search term, so essentially
you were NOT-ing resuscitate as a search.  

When you type quotes around the term it forces PubMed to take the entire
term and search for it as a phrase, in all fields.  Which depending on
the phrase may or may not be good/helpful.  

Resuscitation orders is actually the MeSH term used for do not
resuscitate and articles talking about DNR will be indexed under
Resuscitation orders which yields 2817 citations..
