 The
FIND HEADING/SUBHEADING screen
Find buttons are located to the left of the fields to which
they are linked. One find button is present on the Basic Search
screen and three are found on the Advanced Search screen.
The first find button (Advanced & Basic) is located to the
left of the "Search Phrase" field and, when
clicked, will send the user to the Find Heading/Subheading
screen where you may then submit up to two words and/or phrases
with which to perform a search. The fields may be joined by the
boolean operators AND or OR. Also, the first field
must be filled in order for a search to be submitted and the
second field is optional.
In the following example, the words "back" and
"pain" are entered into the two search fields.
These two words will be joined by the boolean operator AND;
meaning that the search engine will try to locate headings and
subheadings (Medical Subject Headings / Subheadings) with the text
string of "back" AND the text string of "pain"
anywhere within the word. If the boolean operator of OR
were used in it's place, the search engine would pull up more
results because it would be looking for all headings and
subheadings that contained the text string "back" OR the
text string "pain" anywhere within the word.

The
RESULTS screen
After you have decided on your search strategy, you will need
to click the Submit Search button to get your results. If
the search is successful, two tables will be presented to you. The
first table, or the MANTIS™ Headings/Subheadings Table,
contains terms that have been used to index the literature in the
database. These terms consist of BOTH Medical Subject Headings
AND our Supplemental Headings that we have created to index
specific journals covered by MANTIS™. The second table, or the Medical
Subject Headings (MeSH) Table, ONLY contains MeSH terms that
match your query (this table does NOT contain the supplement terms
created by Action Potential, Inc., for use to index literature
included in the MANTIS™ Database).

Using
the EXPLODE and FOCUS options at the results screen
The second table includes some options to help you locate a
term if the one you seek is not listed. These options are the
"Explode" and "Focus" links to
the right of each term listed. There is a hierarchy to MeSH, and
these options allow you to work your way up the tree to a more
general term (Explode) or down the tree to a more specific term
(Focus) to be used. For more information on MeSH terms and their
use, please follow this
link.
Once you have decided on the terms you would like to have
inserted into your search strategy, click on the checkboxes
provided to the right of each of the terms. Upon completion, you
may click on the button labled "Add To Search" at
the bottom of the page. This will send you back to your search
screen (Basic OR Advanced, depending on which you started with)
with those terms inserted into the Search Phrase field and
separated by the boolean operator of "OR".
