.SH DESCRIPTION
\fBentrez\-phrase\-search\fP
is an \fBedirect\fP(1) \fBesearch\fP(1) wrapper script
that searches an NCBI Entrez database for a phrase
rather than discrete keywords.
It works by breaking the query up into pairs of adjacent words
(disregarding connecting words like "the")
and intersecting searches
for word pairs that appear reasonably often.
