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.

       -link  Follow links by the given tag (e.g. CITED), merging any duplicates.

       -words Combine searches for individual informative words.

       -pairs Combine searches for pairs of adjacent informative words.

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

       -totals
              Like -fields, but with term counts.

       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.
