hello sir,

Before doing a search, it's important to define your topic as completely and succinctly as possible. Write down exactly what information you're looking for, why you're looking for it, and what you're not looking for. This will help you to discover the best keywords for your search.

For an effective query -

1. Used Boolean commands (or "operators") AND, OR and AND NOT.

2. Use nouns as query keywords. Never use articles ("a," "the"), pronouns ("he," "it"), conjunctions ("and," "or") or prepositions ("to," "from") in your queries.

3. Use 6 to 8 keywords per query.

4. Where possible, combine keywords into phrases by using quotation marks, as in "solar system".

5. Spell carefully, and consider alternate spellings.

6. Avoid redundant terms.
