DESCRIPTION

       phrase-search  searches  an  indexed  local  NCBI   PubMed   archive   (as   prepared   by
       index-pubmed(1)).

OPTIONS

       -h|-help|--help
              Print usage information.

       -path|-master dir
              Search the local archive in dir.

       -count Print terms and counts, merging wildcards.

       -counts
              Expand wildcards; print individual term counts.

       -query Search on words or phrases in Boolean formulas.

       -filter
              Filter piped-in output from a previous (quite possibly remote) query.

       -exact Strict search for article title round-tripping.

       -terms Interpret  the  query  as a field name, and list that field's known terms.  With an
              empty query, list supported fields.

       query...
              What to search for in the above modes; may contain standard Boolean operators  AND,
              OR, and NOT, using parentheses as needed for grouping.

       -convert dbas type type [key]
              Convert  identifiers  in the specified database from one type to another, accepting
              either a single identifier on the command  line  or  a  newline-delimited  list  on
              standard input.  The database may be any of
              mesh  Medline subject headings in general
              chem  MeSH chemicals
              disz  MeSH diseases
              gene  Genes

              and the type may be any of
              Name  official name
              Code  internal identifier
              Tree  path within MeSH tree (except for gene)
              Desc  description (only for gene)
              Term  synonym (except for gene)

       -lookup tag theme...
              Look  up  cross  references  between internal identifiers read from standard input,
              where tag identifies a pair of databases (e.g., chdi for  chemicals  and  diseases)
              and theme... are theme codes of particular interest (with p and m standing in for +
              and - respectively).

ENVIRONMENT

       EDIRECT_PUBMED_MASTER
              Local archive directory to use in the absence of -path/-master.  Expected  to  hold
              an absolute path; mandatory when not supplying a path on the command line.
