our introductory bio says videos cover basic information about
0:05
indexing and meiosis databases which include biological abstracts bio says
0:10
previews
0:11
and meiosis Citation Index this presentation will cover different ways
0:15
you can take advantage of that indexing to make your search is more precise
0:19
to retrieve smaller sets search results composed
0:22
more highly relevant papers for example
0:26
when you're searching for information about a particular organism
0:29
you can use the taxonomic datafield instead of the topic field
0:33
to reduce the number of false hits or irrelevant records returned
0:37
in addition you can add terms from any of the three by OSA search aids to
0:42
provide focus to an ambiguous search
0:44
or to narrow its topical focus you can also use advanced search to restrict
0:49
your search to a particular geographic region
0:52
geologic time research method disease
0:55
at more
0:58
when you're searching by Isis resources it is generally best to search for
1:02
information about it organism
1:03
by both its common and Latin name as %uh do here by searching for information on
1:08
bottle courts
1:09
I'm using the Bay Osa Citation Index for this example
1:13
but everything covered in this video works in the exact same way
1:17
and biological abstracts unbiased reviews
1:21
when you run your search using the topic field the system looks for your terms in
1:25
many places on article records
1:27
meaning that in addition to finding records like this one
1:30
which discuss bottle gourds and detail
1:36
you may also get records like this one which only incidentally mentions bottle
1:40
gourds in the abstract
1:42
since biosynthetic sirs list each organism discussed substantively in a
1:46
paper in the organism name column at the taxonomic data table
1:51
you can run your search the taxonomic datafield
1:54
instead of the topic field to eliminate records like this one
2:08
this search returned fewer hits than the previous one
2:11
but all of the results discussed that organism I'm interested in
2:15
so they're more on target with what I'm looking for
2:19
the taxonomic datafield also has search it
2:24
here I can search or browse through a controlled list have over a thousand
2:28
organism classifiers
2:29
which are high-level taxonomic terms representing broad categories of
2:33
organisms
2:34
the most granular level up the list is family so if I try to search for a genus
2:39
or species name here
2:40
I won't get any hits
2:43
a quick belongs to the correct AC family
2:48
clicking the Add button will place the corresponding term in the search builder
2:51
at the bottom of the screen
2:55
from here select okay to return to the search page
2:58
and run your search
3:03
clicking the button marked H will show where term falls in that the source
3:06
hierarchy sleep can see if there are any broader or narrower terms that relate to
3:11
your search
3:12
you can see that the hierarchy moves from general to specific as we move from
3:16
left to right
3:17
cooker but AC blogs should more general category called I cuddle Eden's
3:22
which in turn is part of a broader category called angiosperm a
3:27
when a plus sign appears to the left of the term this indicates that more
3:31
specific narrower terms exist below it
3:34
if you choose to search on a term that has narrowed terms beneath it
3:38
the system will not automatically include the narrower terms in your
3:42
search
3:45
in addition to taxonomic data the major concepts
3:49
and concept code fields also have search aids
3:55
use terms from any of the three to focus your topic searches to your area of
4:00
interest
4:03
let's say we're looking for papers on zygotic transcription and to be in San
4:07
reptiles
4:08
I can use the taxonomic did a search aid to restrict my search to those classes
4:13
have animals
4:19
and pair this with the topic search for zygotic transcription
4:27
all the papers return will
4:28
discussed an amphibian or reptile which I can see in the taxonomic table
4:33
and mention zygotic transcription in the title
4:37
abstract for elsewhere on the record
4:41
as you're viewing biases search results you may notice information pulled into
4:45
specific fields like chemical data
4:47
methods and equipment data and parts in structures data
4:51
bio says indexers apply these fields two papers based on the content they discuss
4:56
and you will encounter records with additional fields beyond needs
5:03
sum up the special
5:04
iced fields are searchable from the basic search page
5:08
here I can see that searching the chemical data field is an option
5:12
but they don't see parts and structured or methods and equipment
5:16
to find them on the need to switch to advance search mode
5:21
here I can access a complete list all available search field set by assess
5:27
let's review a selected list have some especially useful Advanced search fields
5:32
you can use the DS tag to search for names have diseases disorders
5:36
are pathological conditions the disease data field may
5:40
also list mesh controlled terms variant terms
5:43
and disease affiliations use the MQ tag to search for methods and equipment data
5:49
such as information about scientific techniques scientific methods and
5:53
specific equipment such as machinery or software
5:56
the parts and structures data table is searched with the PSD tech
6:00
this will search names of parts or components are human
6:04
plant for animal organism as well as organ systems
6:08
you can use the GE tag to search for particular geographic locations
6:13
and the GT tag to search for particular geological time periods
6:20
to enter search here %uh need to use field tags:
6:23
let's say we want to fight articles on rheumatoid arthritis
6:27
where the only sell or enzyme-linked immunosorbent
6:30
as a biochemical technique was used since rheumatoid arthritis is a disease
6:36
are entered the diseases datafield tag DS
6:39
and equal sign and my term as a phrase
6:43
said to lisa is a technique all search for that concept in the method to
6:47
equipment
6:48
field
6:59
all results returned will display rheumatoid arthritis in the diseases
7:02
data table
7:05
and the only set technique under Methods adequate
