Help for Search

Online catalog (IPAC) help.

Page Search allows to enter terms for searching into the search box and to search the records that contain the entered terms (in all the fields, titles, authors, keywords etc.). Page offers a possibility to enter a more complex search term with limits, choose records display format and sorting.

What can you write into the term box?

• more words that will be in the index together regardless of the order technologies information
• more words and from which some of them can be found in the index technologies or information
• one word technologies
• a part of the word – you replace the truncation with an asterisk technolog*
• a phrase in quotation marks – a part of the text „class for the qualified “
• a term starts with a caret ^school – terms will be on the first position in the index

It is not necessary to make a difference between upper and lower case in the term entered because ASCII searching is used as default – it means searching regardless upper/lower case and diacritics.

Special (non-alphanumerical) characters are ignored in the search term. If you use some special character in search term, it will be replaced by space, because the terms are prepared in that way in the index.
Thus e.g. the document title 2 a 1/2 will be added to the index as 2 a 1 2.
If you use special characters in search term, the search could give an error in same case. We recommend to exclude these characters.
The list of special (non-alphanumerical) characters that are ignored in the search terms are as follows:
! @ # $ % ^ & * ( ) - + = [ ] { } \ , . / < > ? ; ' : " |

When and how to use search operators?

It is possible to add more search boxes and to combine queries with operators.
Search operators allow to specify the query.
JavaScript is required for search operators using.

Narrowing the search - operator: and

Can be used for searching records that contain both of the entered terms, A and B.

Widening the search - operator: or

Can be used for searching records that contain at least one of terms, A or B.

Term you want to exclude from the search - operator: not

Can be used for searching records that contain the term A, but don't contain the term B.

As you type into the search box “Suggest” it will guess what you are typing and offer suggestions in the real time. It will help you to search for longer words without typing them whole.

Options

Options that can be used for a term specification are as follows:

all words

all words entered in the term have to be in the index,

phrase

an exact word order entered in the term,

whole phrase

search in the whole phrase index (not in the index with individual words),

at least one of the words

How to use limits?

Limits allow you to narrow the search results by other dimensions (a language of a document, a country of a publication, a date of a publication, etc.).

The number of limits depends on the number and the kind of selected sources. See help for Resources.

In case you select a source that does not support any limits (or only few of them), no other limits will appear. If you would like to use all of the limits, select only one source, or sources of a similar type.
Only options that are supported by all the sources are available in limits selection.

Search settings

In the setting you can choose a type of a record display (Display format) and a preferred records sorting that will be used in a search result. This setting will be used during the searching till the end of the session (it means until you close page IPAC in a browser).

Search settings are available according to the possibilities of sources that you have chosen for searching (page Resources).
Sorting is not usually available for external resources. You can use Basketfor sorting of an adequate number of records from external resources. Add records to the basket and choose a type of sorting that is available there.

As you type into the search box “Suggest” it will guess what you are typing and offer suggestions in the real time. It will help you to search for longer words without typing them whole.
