Search Term Mapping
n   MeSH Translation     n   Forced phrase searching in quotes
    Table                    “”
n   Journals             n   Explode is automatic
    Translation Table    n   Truncation (*) turns off mapping
n   Author Translation   n   Search field tags are available
    Table                    [title] or [ti]
n   Author Index         n   Boolean operators processed left to
                             right
n   Search All Fields




                                                              9
Why use MeSH?
 n   If you use two or more words in a keyword search
     there is no guarantee that they will be linked.

 n   MeSH headings are an efficient way to find
     information on “concepts” or topics where authors
     use different language to discuss the same ideas.

 n   For example: Keyword search physical therapy
     Microneedles and other physical methods for
     overcoming the stratum corneum barrier for
     cutaneous gene therapy.


                                                    10
When to use keyword search?
 n   Recent publications (in process)
 n   Records supplied by publishers
 n   New phenomenon




                                        11
Locating MeSH
 n   Do a Title word search; display results in Citation
     format; identify MeSH

 OR

 n   Search the MeSH database
      n Scope Note

      n Subheadings

      n Major Topics

      n Explode




                                                           12
