Boolean searching concepts
 * 1. The Logic of Search **
 * OR - synonyms (college or university) - To use 'or' logic in search queries, the word OR must be in all capital letters - you can combine several terms or concepts - gives more
 * AND - poverty AND crime - In older databases, the user would need to type the term 'and' to create term-inclusive searches. But today, most search engines use the 'soft' and. That is, if a space is left between terms, the engine assumes you intend AND logic in the query..- gives less
 * NOT - cats NOT dogs - excludes - NOT logic is now expressed by the use of a hyphen (-) in front of a term/word in the query...
 * and it is possible to combine the searching concepts -> bevior AND (cats OR felines) - esimerkkejä: **[clinton -lewinsky] - ****[windows -98 -3.1] kun halutaan vain 95 windows juttuja - **

**The Nyms** Last edited by Emil Ahangarzadeh An oft overlooked concept in online searching is the use of synonyms, hyponyms, and hypernyms. English is an intricate language with many subtleties. Words will always have shades of meaning that are difficult for computers to prioritize. A careful application of nyms can help any search engine find just what you are looking for.

Synonym
<span style="background-color: #ffffff; color: #333333; font-family: 'Helvetica Neue',Helvetica,Arial,sans-serif; font-size: 12.727272033691406px;">If your first search query doesn't retrieve what you are looking for, consider finding new keywords to describe the same concept. One way to do this is to think of synonyms for the terms in your query. Synonyms are words that have the same or nearly the same meaning. Synonyms for //search// would be seek, look, hunt, or quest. Each word might mean the same thing, but there are also shades of meaning that make the word more specific. You can use these shades of meaning to focus your query.

<span style="background-color: #ffffff; color: #333333; font-family: 'Helvetica Neue',Helvetica,Arial,sans-serif; font-size: 17.5px;">Hyponym
<span style="background-color: #ffffff; color: #333333; font-family: 'Helvetica Neue',Helvetica,Arial,sans-serif; font-size: 12.727272033691406px;">A //hypo//nym is a word that describes things more specifically. Proper nouns are good examples of hyponyms. Niagara Falls is a hyponym for the concept of waterfall. Ford is a hyponym for the concept car. Just as a //hypo//dermic needle ends with a very fine point, //hypo//nyms are words that pointedly focus your search. Keywords that are //hypo//nyms will retrieve fewer and more precise results. For this reason, hyponyms narrow a search.

<span style="background-color: #ffffff; color: #333333; font-family: 'Helvetica Neue',Helvetica,Arial,sans-serif; font-size: 17.5px;">Hypernym
<span style="background-color: #ffffff; color: #333333; font-family: 'Helvetica Neue',Helvetica,Arial,sans-serif; font-size: 12.727272033691406px;">//Hyper//nyms are words that refer to broad categories or general concepts. Car or airplane are //hyper//nyms for more precise terms like Toyota Camry, or Boeing 747. If you are not getting enough results you can broaden your search by using //hyper//nyms.

<span style="background-color: #ffffff; color: #333333; font-family: 'Helvetica Neue',Helvetica,Arial,sans-serif; font-size: 12.727272033691406px;">Tällaisella sivustolla keksitään kaikkea netistä tiedon etsimiseen liittyvää http://searchenginewatch.com/ ja sivuilta löytyy myös search engine glossary

Tästä puhutaan http://www.google.com/advanced_search Mutta, paljon fiksumpaa on käyttää Boolen logiikkaa ja muita omia lausekkeita, koska etsiminen niiden avulla on nopeampaa. <span style="background-color: #ffffff; color: #333333; font-family: 'Helvetica Neue',Helvetica,Arial,sans-serif; font-size: 12.727272033691406px;">References

You should also remember that advanced search engine functions are useful (last week) site, **<span style="background-color: #ffffff; color: #333333; font-family: 'Helvetica Neue',Helvetica,Arial,sans-serif; font-size: 12.727272033691406px;">Please note that various search engines use different operators for forcing domains or country codes. For example, Microsoft's Bing search engine uses //location://. Other search engines use //host://. **
