DESCRIPTION

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

OPTIONS

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

       -path 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 round-tripping.

       -title Exact search limited to indexed title field.

       -words Combine searches for individual informative words.

       -pairs Combine searches for pairs of adjacent informative words.

       -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.
