Search tool and search strategies
Alhamdulillah, now we are in topic three which is all about search tool and search strategies. In this topic at first we concerned with the library catalogs. Library catalog system supposedly refer to the information retrieval system. With the help of this system we can easily find out any books or periodicals from the library. As well as this system gives us the information and guidance on how to conduct with the
library catalog system. Furthermore during this period we also came to know
about the library OPAC system which actually stands for Online Public Access
Catalog. This system serves us focal search point for our library system. We
can search by the name of title, author, publisher or date of publication to
find out any book. By finding out any book in sort time this system helps us to
save our time.
In this session we have learnt about the information search tools which are actually related with
the internet, because with the help of internet we can find out any information
within a second. Due to this reason internet is considered as one of the best
tools for searching any kind of information. Now a day’s internet has become
the environment of information where we can find out any kind of information
without any delay. Internet constitutes a large number of search engines to get
available information. The great example of search engines are Google, Alta
Vista, Being, yahoo, ask.com, live search and so on. To acquire any kind of
information we can use these engines.
During this topic our another main lesson
was connected with the specialized databases. At the beginning of the class our
lecturer asked us some brief question about the previous topic which was on
information search tools. When she recognized that the previous lesson was done
then she proceeds with the next topic. At first she introduced us with the
general knowledge about the database and to continue she showed us some of the
slide show on it. As far as I understand about the online database it is a
collection of computerized information or data such as articles, books,
graphics and multimedia that can be searched to find information.
To continue our
class, she started with the database search engine. In order to search any
information by using the online system, we can follow two ways which are simple
screen search and advanced screen search. The example of simple screen search
is Google search which is used by most of the user to find out any kind of
information. And the example of advanced screen search is the searching tool
which we use to get more information about the topic. We can search any
information by mentioning the topic, keyword or full text.
The new thing
which I have gained from this topic was, if we want to search any information
about any topic what we have to mention in order to get the right information.
For getting actual information about any topic we can search by subject,
keyword or full text. At what time we should use which method it depends on the
topic .Again we can also search by using media type and using phrase, instead
of using the whole sentence for searching essential information. We can use phrase
to find out any suggestions in short time. It will save our time and provide us
the needed information.
Finally, with the truncation and wildcard we have finish this topic . First of all
our Miss explained us what is the meaning of truncation and wildcard, and in
which way we should use these two method to get the needed information. She
narrated all the important point about this topic by using her informative
slide show.First of all
our Miss explained us what is the meaning of truncation and wildcard, and in
which way we should use these two method to get the needed information. She
narrated all the important point about this topic by using her informative
slide show. From this class I came to know about this topic which is
'Truncation and Wildcard both assists us to broaden our search in order to have
appropriate information about the topic’. Moreover in this search we may also
use retrieve multiple spelling of the synonyms. These search systems expand the
search to locate all the words at the beginning with the same root. During this
class our respective Miss gave us a lot of meaningful example to clarify our
concepts about this topic. By attending this informative class I was able to
have a clear concept about the lesson.
To continue this
class she started with the phrase searching. Before go through to the new topic
our respective lecturer again reminded us about the previous topic. She asked
us several questions to make sure that we understand the previous one. To make clear
she again re-explained the previous topic. Formerly, our lecturer started with
the new part which is phrase searching. Usually phrase searching is used when
we use a strings word instead of a single word. But there is a disadvantage of
using phrase searching which is retrieving less information. As a great example
if we want to search for 'information literacy' then we can use this phrase
searching system and it will give us the meaning of the whole word. But at a
same time if we search word by word it will give us more information. In the
system of phrase searching we can use bracket or inverted comma for the
database to understand our search. And these are all what we have learned from
topic three.
