[Biopython] search Entrez with boolean operators

[Thomas Evangelidis]

Dear all,

is it possible to set the term parameter in Bio.Entrez.esearch() accordingly
so that it will search Entrez using boolean operators? I tried myself
several combinations with no luck. For instance lets say I want to query All
Fields of PubMed using this whole phrase (not intividual words): "ABC efflux
transporter", how should I write it?

thanks in advance.
