Useful Search Tips

If you are not sure about writing a wor

You should use symbols ? or *.
Type the word, substituting the one unknown letter by symbol ? and a few unknown letters by *. For example:

communi?a?ion

communica*n

 Note  You can’t use the * or? symbols as the first character of the word.

If you want to fulfil an exact search by word or phrase

You should put the word or the phrase in quotation marks. For example:

"Sociality as negativity"

If you want to extend the search

you should use the * symbol, which replaces any number of characters at the end of the word.

For searching for words a education, educative, educational, etc .:

educat*

If you need that all words of search query are available in the description of each found document

You should type the words separating them by SPACE or combining them by the logical operator AND. For example:

Murphy's law

law AND Murphy

If you need to find documents that match any word of the search query

Use the logical operator OR. For example:

capital OR finance

If you need to exclude a word from the search

Put a - (minus sign) or a logical operator NOT before the word you want to exclude. For example:

"the Poincaré –theorem"

or

"theorem NOT Poincaré"

the search results will not contain the documents about the Poincaré theorem.

 Note  The logical operators should be typed only in capital Latin letters, separating them from the search words only by one space. Symbols *, - (minus) are not separated by a space from the word to which they are related.

If you have to complete a complex search

You should combine the known symbols and operator. For example:

pr?mary  sch*ls  OR pr?mary  cla?s  AND ma*ematics
