It is important to determine the search strategy to find any information. The more care is taken in this search technique, the more useful and necessary information will be found. A good search strategy saves a lot of time in searching for information, gives an opportunity to search in different places, and helps to find a lot of useful information.

So a search strategy is a specific plan for finding information that is developed in the following steps:

1. To be absolutely sure about the question or matter;

2. Identify key words or phrase-based words from questions;

3. To identify synonyms or related words;

4. Formulation of search statement;

5. Initiating a search;

6. Evaluating search results;

7. Search and save the results

Mainly, three main techniques are used to search for information. They are:

A. Selects key words;

B .Using truncation;

C .Using the Boolean operator;

A. Key words: When looking for information on a subject, first select the key words that can accurately describe the subject. Many times it is not even thought that the subject can be found with one or more key words. So the other words to look out for in this regard are –

Synonyms such as -submarine or submersible or underwater may provide information on the same subject.
Do not use nouns (singular, plural) at the end of words;
Alternative spellings should be considered such as Labor according to the American spelling rules and Labor according to the British spelling rules.
Be aware of acronyms like ‘Gallium arsenide’ or ‘GAAS’, ‘Computer aided design’ or ‘CAD’.

B. Letter compression and Wall card technique: This technique is used for searching if you do not know the correct spelling of a word or if you are in doubt. In this technique the two symbols ‘*’ and ‘?’ is used. Multiple characters are represented by the * symbol and a single character by the? Symbol.

For example, the word COMPUT with the help of the, comput * technique is searched with the words compute, computable, computer, computers, computing, computation.

If in doubt about one or more letters in the word in the wild card system, replace that letter? Or $ fetches all possible word information and selects the required information from there.

such as organi ? ation word ‘?’ The sign helps to remove the doubt that S will not be J at that place. That is, with the help of this technique, information can now be extracted using both the words organiSation and organization. For example if in doubt with psychology spelling, we can use the wildcard method with $$$chology$ or??ychology etc.

C Boolean logic:

This method is used to extract very useful and controlled data. Boolean logic uses three techniques: And, Or, Not. The Boolean technique is easily understood with the help of a Venn diagram.

The most controlled and most useful information is obtained with the help of AND techniques. In the example above, the black area in the left box (poverty and crime) provides very little but useful information.

The OR technique yields the largest number of data. In the middle box of the Venn diagram above, the two spheres are marked with black symbols that provide both college and university information.

The NOT technique is used to extract useful information from the original search if the irrelevant information is excluded. For example, in the box on the right side of the Venn diagram above, a circle with some parts white and some black marked with cat’s gives information that somehow does not contain dogs.

Other search strategies are:

Phrase-based search:

In this case, the actual phrase from the search is identified by the symbol “ “.For example, the phrase “operating system” will retrieve only those documents that contain the two words together.

B. Stop words:

The search is much more controlled by excluding the stop words at the beginning of the search. Words that are often used to form sentences in the languages we normally write, read or speak are not used as search terms. These words are called Stop Words like the, an in, of, a, this, that, etc.

C. AND or NOT:

+ Sign is used to indicate requirement and -sign to indicate exclusion. Like: +fraud or -election etc.

D.NEAR:

NEAR is often used to get nearby information. Like “Salman Rushdie NEAR tearowel .

E. NESTING:

NESTING techniques are used to combine multiple terms with Boolean, and then extract the final regularized data. For example -Marx NOT (Brothers OR Moscow); (Jesus Christ “NOT Humor) and (Mary OR Magdalene)

Whatever search strategy is used, to get good results, the topic and objectives must be clearly defined before using any strategy. Then choose the right search strategy to meet that goal. Keeping a proper record of every search is to get accurate, useful information for the future or to make the search smoother. Vague or vague words and misspellings should not be used to search for a topic.
