Search Tips
The simplest way of searching for words is to type several of them after one another, separated by blank spaces. The following information should help you to create more complex queries which provide more complex and clearer results.
It is often the case that you look for a word which can appear in different forms, but beginning with the same sequence of letters, e.g. when you enter dig*, the programme will find not only the word dig, but also digs, digger, digging, etc.
You can also use the ability of the search engine to find all forms of a certain word. When you type sink**, you will also find documents containing not only the words sink and sinking, but also sank a sunk.
It is better to use the NEAR keyword, rather than the AND keyword; NEAR can find documents, in which the keywords are close to each other. Both the air and pollution and air near pollution queries will return pages on which both the words air and pollution appear. When using NEAR, however, those pages get to the top of the list in which the two words are close to each other; the closer they are to each other the higher their priority.
The results of the queries can also be enhanced by using the key words AND NOT to eliminate certain words, e.g. if you want to find all occurrences of the word money, which do not appear together with work, simply type the following:
money AND NOT work
money OR work
This query returns all pages containing either the word money, or the word work, or both.
When searching for exact phrases, put them in parentheses.
Use Free Text queries and ask straightforward
questions. Example:
"How to use tables in HTML?"
NB When using Free Text queries, AND, OR and NEAR
are interpreted as normal words.
Please note that the more complex query you enter, the longer it takes to be processed. Therefore please be patient. If you have any questions or comments, mail us at support@ecn.cz, or call +420 (2) 311 81 70.
